electrical description the sil/SMT80C2 is implemented using a multi-phase synchronous buck topology. a block diagram of the converter is shown in figure 1. the output is adjustable over a range of 0.8375-5.1 v b y u sing a r esistor fr om the tr im p in t o -trim pin, or by driving the trim pin with a v oltage. the converter can be shut down via the enable p in. this input is run with positive logic that is c ompatible with popular logic devices. positive logi c implies that the converter is enabled if the in put is high (or foating), and disabled if it is low. output is monitored for overcurrent and short- circuit conditions. when the pwm controller de tects an overcurrent condition, it forces the m odule into hiccup mode. a typical application is shown in figure 2. wide operating temperature range the sil/SMT80C2's ability to accommodate a wide r ange of ambient temperatures is the result of its e xtremely high power conversion effciency and r esultant low power dissipation, combined with the e xcellent thermal performance of the pcb substrate. m aximum output power that the module can deliver de pends on a number of parameters, primarily: ? input voltage range ? output load current ? air velocity (forced or natural convection) ? mounting orientation of target application pcb, i.e., vertical/horizontal mount, or mechanically tied d own (especially important in natural convection conditions). ? target application pcb design, especially ground planes. these can be effective heatsinks for the con - verter. the sil/SMT80C2 module has an operating temperature range of 0 c to 85 c with suitable derating and/ or forced air cooling. i limit l out v out gnd remote on/off pwrgd tr im vo ut vi n phase 1 phase 2 upper g/drive upper g/drive lower g/drive lower g/drive 1 l out 2 phase 3 upper g/drive lower g/drive l out 3 phase 4 upper g/drive lower g/drive l out 4 sil80c2 rev. 04.25.11 sil/SMT80C2 2 of 20 embedded power for business-critical continuity technical reference note general description figure 1 - electrical block diagram f igure 2 - standard application drawing 5 12-14 9 15,16,18, 20,22,24 10 sil80c2 enable on/off v in gnd r trim c in r l o a d v out c out 1 11 +sense -sense r uvlo ishare 6 4 power good gnd 3,7,8,17, 19,21,23

rev. 04.25.11 sil/SMT80C2 4 of 20 embedded power for business-critical continuity technical reference note power good the sil/SMT80C2 modules have a power good indicator output. this output pin uses positive logic and is o pen collector. also, the power good output is able to sink 1 ma. the power good signal should not be p ulled any higher than 5.1 v. when the output of the module is within 10% of the nominal set point, the power good pin can be pulled hi gh. ov ertemperature protection (otp) the sil/SMT80C2 is equipped with non-latching overtemperature protection. a temperature sensor m onitors the temperature of the pcb near one the main fets. if the temperature exceeds a threshold of 150 c (typical) the converter will shut down, disabling the output. when the substrate temperature has decr eased by 10 c the converter will automatically restart. the converter might experience overtemperature conditions during a persistent overload on the output. ov erload conditions can be caused by external faults. otp might also be entered due to a loss of control o f the environmental conditions (e.g. an increase in the converters ambient temperature due to a failing f an). features and functions

technical reference note output voltage adjustment (cont'd) the trim equation for the basic confguration shown in figure 5 is: r tr im (k) = 1.675 v out - 0.8375 where vout is the desired output voltage, rtrim is the resistance required between trim and -trim. the trim equation for the external voltage confguration shown figure 6 is: r tr im2 (k) = r tr im1 (1.2 - 2vt) r trim1 (vout - 0.8375) - 1.675 where vout is the desired output voltage, rtrim1 and rtrim2 are the resistors in figure 6 and vt is the applied external voltage. the trim equation for the potentiometer confgurations shown in figure 7 is: v out = 0.8375 (r tr im2 + rpot)r trim1 x (2r trim2 + 2r pot + r trim1 r trim2 + r trim1 r pot + 2 rtrim1 ) where vout is the desired output voltage, rtrim1 and rtrim2 are the resistors in figure 7 and rpot is the resistance of the potentiometer. undervoltage lockout the sil/SMT80C2 has built-in undervoltage lockout to ensure reliable output power. the lockout prevents the unit from operating when the input voltage is too low. the uvlo for the sil/SMT80C2 can be adjust - ed with the following equation: the trim equation for the undervoltage lockout is: r u vlo (k) = 124.8 + v turn_on 10 v turn_on - 42.06 rev. 04.25.11 sil/SMT80C2 6 of 20 embedded power for business-critical continuity application (c ont'd)
technical reference note remote sense compensation the remote sense compensation feature minimizes the effect of resistance in the distribution system and facilitates accurate voltage regulation at the load terminals or another selected point. the remote sense lines will carry very little current and hence do not require a large cross-sectional area. however, if the sense lines are routed on a pcb, they should be located close to a ground plane in order to minimize any noise coupled onto the lines that might impair control loop stability. the module will compensate for a maximum drop of 400 mv. remember that when using remote sense compensation all the resist - ance, parasitic inductance and capacitance of the distribution system are incorporated into the feedback loop of the power module. this can have an effect on the modules compensation capabilities, affecting its stability and dynamic response. parallel operation parallel operation of multiple converters is available since the sil/SMT80C2 has a current sharing option. the converter will share to within 10% of full load. to current share, pin 6 of each module should be connected. also, the remote sense lines should be connected at the same point. figure 9 shows the typical current sharing application. rev. 04.25.11 sil/SMT80C2 7 of 20 embedded power for business-critical continuity figure 9 - parallel application vi n 12-14 vo ut sil80c2 tr im -trim ishare 6 gnd 11 sense- 10 sense+ vi n 12-14 vo ut sil80c2 tr im -trim ishare 6 gnd 11 sense- 10 sense+ r l o a d cload application (c ont'd)
technical reference note rev. 04.25.11 sil/SMT80C2 8 of 20 embedded power for business-critical continuity output capacitance the sil/SMT80C2 has output capacitors inside the converter. no output capacitance is required for stable operation. when powering loads with large dynamic current requirements, improved voltage regulation is obtained by inserting low esr capacitors as close as possible to the load. low esr ceramic capacitors will handle the short duration high frequency components of the dynamic current requirement. in addition, higher values of electrolytic capacitors should be used to handle the mid- frequency components. it is equally important to use good design practices when configuring the dc distribution system. low resistance and low inductance pcb layout traces should be utilized, particularly in the high current output section. remember that the capacitance of the distribution system and the associated esr are within the feedback loop of the power capabilities, thus affecting the stability and dynamic response of the module. note that the maximum rated value of output capacitance varies between models and for each output voltage setpoint. a stability vs. load capacitance calculator, (see your sales representative), details how an external load capacitance influences the gain and phase margins of the sil/SMT80C2 . smt reflow guidelines for a snpb process: pads should be above 183c (liquidus) for 90 seconds max (60-75 seconds typical) with a peak temperature of 225c. for a leadfree sac305 process: pads should be above 217c (liquidus) f or 90 seconds max (60-75 seconds typical) with a peak temperature of 250c. w ater washing not recommended. application (c ont'd)
