  ? semiconductor components industries, llc, 2017 october, 2017 ? rev. 7 1 publication order number: NCP1060/d NCP1060, ncv1060, ncp1063, ncv1063 high-voltage switcher for low power offline smps the ncp106x products integrate a fixed frequency current mode controller with a 700 v mosfet. available in a pdip?7, soic?10 or soic?16 package, the ncp106x offer a high level of integration, including soft?start, frequency?jittering, short?circuit protection, skip?cycle, adjustable peak current set point, ramp compensation, and a dynamic self?supply (eliminating the need for an auxiliary winding). unlike other monolithic solutions, the ncp106x is quiet by nature: during nominal load operation, the part switches at one of the available frequencies (60 khz or 100 khz). when the output power demand diminishes, the ic automatically enters frequency foldback mode and provides excellent efficiency at light loads. when the power demand reduces further, it enters into a skip mode to reduce the standby consumption down to a no load condition. protection features include: a timer to detect an overload or a short?circuit event, overvoltage protection with auto?recovery and ac input line voltage detection (a version). the on proprietary integrated over power protection (opp) lets you harness the maximum delivered power without affecting your standby performance simply via external resistors. for improved standby performance, the connection of an auxiliary winding stops the dss operation and helps to reduce input power consumption below 50 mw at high line. ncp106x can be seamlessly used both in non?isolated and in isolated topologies. features ? built?in 700 v mosfet with r ds(on) of 34  (NCP1060) and 11.4  (ncp1063) ? large creepage distance between high?voltage pins ? current?mode fixed frequency operation ? 60 khz or 100 khz (130 khz on demand) ? adjustable peak current: see below table ? fixed ramp compensation ? direct feedback connection for non?isolated converter ? internal and adjustable over power protection (opp) circuit ? skip?cycle operation at low peak currents only ? dynamic self?supply: no need for an auxiliary winding ? internal 4 ms soft?start ? auto?recovery output short circuit protection with timer?based detection ? auto?recovery overvoltage protection with auxiliary winding operation ? frequency jittering for better emi signature ? no load input consumption < 50 mw ? frequency foldback to improve efficiency at light load ? ncv prefix for automotive and other applications requiring unique site and control change requirements; aec?q100 qualified and ppap capable ? these devices are pb?free and are rohs compliant typical applications ? auxiliary / standby isolated and non?isolated power supplies ? power meter smps ? wide vin low power industrial smps www. onsemi.com pdip?7 case 626a ap suffix 1 8 marking diagrams see detailed ordering and shipping information in the package dimensions section on page 28 of this data sheet. ordering information soic?10 case 751bq ad or bd suffix soic?16 case 751b?05 d suffix 1 10 x = power switch circuit on?state resistance x = (0 = 34  , 3 = 11.4  ) f = brown in (a = yes, b = no) yyy = oscillator frequency yyy = (060 = 60 khz, 100 = 100 khz) z = p (standard) or v (automotive) u = blank (standard) or v (automotive) a = assembly location l, wl = wafer lot y, yy = year w, ww = work week g or  = pb?free package p106xfyyy awl yywwg u1060fyyy alywx  1 10 ncz1063fyyyg awlyww 1 16 1 16 1 7

NCP1060, ncv1060, ncp1063, ncv1063 www. onsemi.com 15 application information introduction the ncp106x offers a complete current?mode control solution. the component integrates everything needed to build a rugged and cost effective switch?mode power supply (smps) featuring low standby power. the quick selection table, table 5, details the differences between references, mainly peak current setpoints, r ds(on) value and operating frequency. ? current?mode operation: the controller uses current?mode control architecture. ? 700 v ?_ power mosfet: due to on semiconductor very high voltage integrated circuit technology, the circuit hosts a high?voltage power mosfet featuring a 34  or 11.4  r ds(on) ? tj = 25 c. this value lets the designer build a power supply up to 7.8 w or 15.5 w operated on universal mains. an internal current source delivers the startup current, necessary to crank the power supply. ? dynamic self?supply: due to the internal high voltage current source, this device could be used in the application without the auxiliary winding to provide supply voltage. ? short circuit protection: by permanently monitoring the comp line activity, the ic is able to detect the presence of a short?circuit, immediately reducing the output power for a total system protection. a t scp timer is started as soon as the comp current is below threshold, i compfault , which indicates the maximum peak current. if at the end of this timer the fault is still present, then the device enters a safe, auto?recovery burst mode, affected by a fixed timer recurrence, t recovery . once the short has disappeared, the controller resumes and goes back to normal operation. ? built?in vcc over v oltage protection: when the auxiliary winding is used to bias the v cc pin (no dss), an internal comparator is connected to v cc pin. in case the voltage on the pin exceeds a level of v ovp (18 v typically), the controller immediately stops switching and waits a full timer period (t recovery ) before attempting to restart. if the fault is gone, the controller resumes operation. if the fault is still there, e.g. a broken opto?coupler, the controller protects the load through a safe burst mode. ? line detection: an internal comparator monitors the drain voltage as recovering from one of the following situations: ? short circuit protection, ? v cc ovp is confirmed, ? uvlo, ? tsd ? if the drain voltage is lower than the internal threshold (v hv(en) ), the internal power switch is inhibited. this avoids operating at too low ac input. this is also called brown?in function in some fields. for applications not using standard ac mains (24 vdc industrial bus for instance), the b version doesn?t incorporate this line detection and let the device start as soon as voltage supply reaches v start(min). ? frequency jittering: an internal low?frequency modulation signal varies the pace at which the oscillator frequency is modulated. this helps spreading out energy in conducted noise analysis. to improve the emi signature at low power levels, the jittering remains active in frequency foldback mode. ? soft?start: a 4 ms soft?start ensures a smooth startup sequence, reducing output overshoots. ? frequency foldback capability: a continuous flow of pulses is not compatible with no?load/light?load standby power requirements. to excel in this domain, the controller observes the comp pin current information and when it reaches a level of i compfold , the oscillator then starts to reduce its switching frequency as the feedback current continues to increase (the power demand continues to reduce). it can go down to 25 khz (typical) reached for a feedback level of i compfold(end) (100  a roughly). at this point, if the power continues to drop, the controller enters classical skip?cycle mode. ? skip: if smps naturally exhibits a good efficiency at nominal load, it begins to be less efficient when the output power demand diminishes. by skipping un?needed switching cycles, the ncp106x drastically reduces the power wasted during light load conditions. ? ipeak set: if current in range 26  a and 285  a is drawn from the pin, the peak current is proportionally reduced down to 40% of its original value. this feature enables to designer to set up the peak current to the value which is ideal for the application. by routing a portion of the negative voltage present during the on?time on the auxiliary winding to the lim/opp pin, the user has a simple and non?dissipative means to alter the maximum peak current setpoint as the bulk voltage increases.
NCP1060, ncv1060, ncp1063, ncv1063 www. onsemi.com 16 application information startup sequence when the power supply is first powered from the mains outlet, the internal current source (typically 8.0 ma) is biased and charges up the v cc capacitor from the drain pin. once the voltage on this v cc capacitor reaches the v cc(on) level (typically 9.0 v), the current source turns off and pulses are delivered by the output stage: the circuit is awake and activates the power mosfet if the bulk voltage is above v hv(en) level (87 v typically) for a version and if bulk voltage is above v start(min) (21 v dc) for b version. figure 30 details the simplified internal circuitry. + ? v cc(on) v cc(min) i start1 v bulk 5 8 1 c vcc r limit i1 i cc1 i2 vcc > 18 v ?  ovp fault drain +? v ovp figure 30. the internal arrangement of the start?up circuitry being loaded by the circuit consumption, the voltage on the v cc capacitor goes down. when v cc is below v cc(min) level (7.5 v typically), it activates the internal current source to bring v cc toward v cc(on) level and stops again: a cycle takes place whose low frequency depends on the v cc capacitor and the ic consumption. a 1.5 v ripple takes place on the v cc pin whose average value equals (v cc(on) + v cc(min) )/2. figure 31 portrays a typical operation of the dss.

NCP1060, ncv1060, ncp1063, ncv1063 www. onsemi.com 18 fault condition ? output short?circuit as soon as v cc reaches v cc(on) , drive pulses are internally enabled. if everything is correct, the auxiliary winding increases the voltage on the v cc pin as the output voltage rises. during the start?sequence, the controller smoothly ramps up the peak drain current to maximum setting, i.e. i ipk , which is reached after a typical period of 4 ms. when the output voltage is not regulated, the current coming through comp pin is below i compfault level (40  a typically), which is not only during the startup period but also anytime an overload occurs, an internal error flag is asserted, ipflag, indicating that the system has reached its maximum current limit set point. the assertion of this flag triggers a fault counter t scp (48 ms typically). if at counter completion, i pflag remains asserted, all driving pulses are stopped and the part stays off in t recovery duration (about 400 ms). a new attempt to re?start occurs and will last 48 ms providing the fault is still present. if the fault still affects the output, a safe burst mode is entered, affected by a low duty?cycle operation (11%). when the fault disappears, the power supply quickly resumes operation. figure 32 depicts this particular mode: figure 32. in case of short?circuit or overload, the ncp106x protects itself and the power supply via a low frequency burst mode. the v cc is maintained by the current source and self?supplies the controller. ipflag timer drv internal 48 ms typ. 400 ms typ. fault open loop fb v cc(on) v cc(min) v cc v comp auto?recovery over voltage protection the particular ncp106x arrangement offers a simple way to prevent output voltage runaway when the optocoupler fails. as figure 33 shows, a comparator monitors the v cc pin. if the auxiliary pushes too much voltage into the c vcc capacitor, then the controller considers an ovp situation and stops the internal drivers. when an ovp occurs, all switching pulses are permanently disabled. after t recovery delay, it resumes the internal drivers. if the failure symptom still exists, e.g. feedback opto?coupler fails, the device keeps the auto?recovery ovp mode. it is recommended insertion of a resistor ( r limit ) between the a uxiliary dc level and the v cc pin to protect the ic against high voltage spikes, which can damage the ic, and to filter out the vcc line to avoid undesired ovp activation. r limit should be carefully selected to avoid triggering the ovp as we discussed, but also to avoid disturbing the v cc in low / light load conditions. self?supplying controllers in extremely low standby applications often puzzles th e designer. actually, if a smps operated at nominal load can deliver an auxiliary voltage of an arbitrary 16 v (v nom ), this voltage can drop below 10 v (v stby ) when entering standby. this is because the recurrence of the switching pulses expands so much that the low frequency re?fueling rate of the v cc capacitor is not enough to keep a proper auxiliary voltage.

t ambmax r  ja (eq. 10) which gives around 870 mw for an ambient of 50 c and a maximum junction of 150 c. if the surface is not large enough, the r ja is growing and the maximum power the device can evacuate decreases. figure 49 gives a possible layout to help drop the thermal resistance. figure 49. a possible pcb arrangement to reduce the thermal resistance junction?to?ambient bill of material: c1 bulk capacitor, input dc voltage is connected to the capacitor c2, r1, d1 clamping elements c3 vcc capacitor ok1 optocoupler r2 resistor to setting i peak current table 5. ordering information device frequency r ds(on) brown in package type shipping NCP1060ap060g 60 khz 34 yes pdip?7 (pb?free) 50 units / rail NCP1060ap100g 100 khz 34 yes 50 units / rail NCP1060ad060r2g 60 khz 34 yes soic?10 (pb?free) 2500 / tape & reel NCP1060ad100r2g 100 khz 34 yes 2500 / tape & reel NCP1060bd060r2g 60 khz 34 no 2500 / tape & reel ncv1060bd060r2g* 60 khz 34 no 2500 / tape & reel NCP1060bd100r2g 100 khz 34 no 2500 / tape & reel ncp1063ap060g 60 khz 11.4 yes pdip?7 (pb?free) 50 units / rail ncp1063ap100g 100 khz 11.4 yes 50 units / rail ncp1063ad060r2g 60 khz 11.4 yes soic?16 (pb?free) 2500 / tape & reel ncv1063ad060r2g* 60 khz 11.4 yes 2500 / tape & reel ncp1063ad100r2g 100 khz 11.4 yes 2500 / tape & reel *ncv prefix for automotive and other applications requiring unique site and control change requirements; aec?q100 qualified and ppap capable.
