icf series wide input 1000 watt isolated full brick dc- dc www.murata - ps.com/support mdc_icf_a01 page 6 of 16 technical notes input fusing the icf converters do not provide internal fusing a nd therefore in some applications external input fuse may be requir ed. use of external fuse is also recommended if there is possi bility for input voltage reversal. for greatest safety, it is recomm ended to use fast blow fuse in the ungrounded input supply line. input reverse polarity protection the icf converters do not have input reverse polari ty. if input voltage polarity is reversed, internal diodes will become forward biased and draw excessive current from the power so urce. if the power source is not current limited or input fuse n ot used, the converter could be permanently damaged. input undervoltage protection input undervoltage lockout is standard with this co nverter. the icf converter will start and regulate properly if the r amping-up input voltage exceeds turn-on threshold of typ. 8.5v (see specification) and remains at or above turn-on threshold. the converter will turn off when the input voltage drops below the turn-off threshold of typical 8v (see specification ) and converter enters hiccup mode and will stay off for 2 seconds. the converter will restart after 2 seconds only if the input volt age is again above the turn-on threshold. the built-on hysteresis and 2 second hiccup time pr events any unstable on/off operation at the low input voltage near turn-on threshold. user should take into account for ir and inductive voltage drop in the input source and input power lines and make sur e that the input voltage to the converter is always above the turn-off threshold voltage under all operating conditions. start-up time the start-up time is specified under two different scenarios: a) startup by on/off remote control (with the input vo ltage above the turn-on threshold voltage) and b) start-up by a pplying the input voltage (with the converter enabled via on/of f remote control). the startup times are measured with maximum resisti ve load as: a) the interval between the point when the ramping input voltage crosses the turn-on threshold and the output voltag e reaches 90% of its nominal value and b) the interval betwee n the point when the converter is enabled by on/off remote cont rol and time when the output voltage reaches 90% of its nominal value. when converter is started by applying the input vol tage with on/off pin active there is delay of 500msec that wa s intentionally provided to prevent potential startup issues especi ally at low input voltages input source impedance because of the switching nature and negative input impedance of dc-dc converters, the input of these converters mus t be driven from the source with both low ac impedance and dc i nput regulation. the icf converters are designed to operate without external components as long as the source voltage has very l ow impedance and reasonable voltage regulation. howeve r, since this is not the case in most applications an additional input capacitor is required to provide proper operations of the icf co nverter. specified values for input capacitor are recommenda tion and need to be adjusted for particular application. due to l arge variation between applications some experimentation may be ne eded. in many applications, the inductance associated wit h the distribution from the power source to the input of the converter can affect the stability and in some cases, if exce ssive, even inhibit operation of the converter. this becomes of great consideration for input voltage at 12v or below. the dc input regulation, associated with resistance between input power source and input of the converter, plays sign ificant role in particular in low input voltage applications such a s 12v battery systems. note that input voltage at the input pins of the co nnector must never degrade below turn-off threshold under all lo ad operating conditions. note that in applications with high pulsating loads additional input as well as output capacitors may be needed. in addi tion, for emi conducted measurement, due to low input voltage it is recommended to use 5h lisns instead of typical 50 h lisns. input/output filtering input capacitor minimum required input capacitance, mounted close t o the input pins of the converter, is 1000f with esr < 0.1v. several criteria need to be met when choosing input capacitor: a) type of capacitor, b) capacitance to provide additi onal energy storage, c) rms current rating, d) esr value that w ill ensure that output impedance of the input filter is lower than input impedance of the converter and its variation over the tempera ture. since inductance of the input power cables could ha ve significant voltage drop due to rate of change of input current di (in)/ dt during transient load operation, an external capacitor on the output of the converter is required to reduce di (in)/ dt . another constraint is minimum rms current rating of the input capacitors which is application dependent. one component of input rms c urrent handled by input capacitor is high frequency compon ent at switching frequency of the converter (typ. 400khz) and is specified under input terminal ripple current i c . typical values at full rated load and 24 vin are provided in section characteristic waveforms for each model and are in range of 2.5a (28vout) C 3.6a (24vout). it is recommended to use ceramic cap acitors for attenuating this component for input terminal rippl e current, which is also required to meet requirement for conducted emi (see emi
www.murata - ps.com/support mdc_icf_a01 page 7 of 16 icf series wide input 1000 watt isolated full brick dc-dc section). the second component of the input ripple current is due to pulsating load current being reflected to the in put and electrolytic capacitors usually used for this purpo se need to be selected accordingly. using several electrolytic ca pacitors in parallel on the input is recommended. esr of the electrolytic capacitors, need to be care fully chosen taken into account temperature dependence. output capacitor similar considerations apply for selecting external output capacitor. for additional high frequency noise atte nuation use of ceramic capacitors is recommended while in order to provide stability of the converter during high pulsating lo ad high value electrolytic capacitor is required. it is recommend ed to use several electrolytic capacitors in parallel in order to red uce effective esr. note that external output capacitor also reduces sl ew rate of the input current during pulsating load transients as d iscussed above. we recommend 2 x 470uf (<40m total esr) or 3 x 330 uf as minimum external output capacitance. on/off (pins 1 and 2) the on/off pin is used to turn the power converter on or off remotely via a system signal and has positive logic . a typical connection for remote on/off function is shown in f ig. 1. fig. 1: circuit configuration for on/off function. the positive logic version turns on when the on/off pin is at logic high and turns off when at logic low. the converte r is on when the on/off pin is either left open or external volt age greater than 2v and not more than 12v is applied between on/off pin and C input pin. see the electrical specifications for lo gic high/low definitions. the negative logic version turns on when the on/off pin is at logic low and turns off when at logic high. the co nverter is on when the on/off pin is either shorted to Cinput pin or kept below 0.8v. the converter is off when the on/off pi n is either left open or external voltage not more than 12v is appli ed between on/off pin and Cinput pin. see the electrical speci fications for logic high/low definitions. the on/off pin is internally pulled up to typically 4.5v via resistor and connected to internal logic circuit via rc circ uit in order to filter out noise that may occur on the on/off pin. a properly de- bounced mechanical switch, open-collector transisto r, or fet can be used to drive the input of the on/off pin. the device must be capable of sinking up to 0.36ma at a low level volt age of 0.8 v. during logic high, the typical maximum voltage at o n/off pin (generated by the converter) is 4.5v, and the maxim um allowable leakage current is 160a. if not using the remote o n/off feature leave the on/off pin open . ttl logic level - the range between 0.81v and 2v i s considered the dead-band. operation in the dead-band is not re commended. external voltage for on/off control should not be a pplied when there is no input power voltage applied to the conv erter. output overcurrent protection (ocp) the converter is protected against overcurrent or s hort circuit conditions. upon sensing an overcurrent condition, the converter will switch to constant current operation and there by begin to reduce output voltage. when the output voltage drop s below approx. 50% of the nominal value of output voltage, the converter will shut down. once the converter has shut down, it will attempt t o restart nominally every 2 seconds. the attempted restart wi ll continue indefinitely until the overload or short circuit co nditions are removed or the output voltage rises above 50% of it s nominal value. once the output current is brought back into its sp ecified range, the converter automatically exits the hiccup mode a nd continues normal operation. during initial startup if output voltage does not e xceed typical 50% of nominal output voltage within 500 msec after the converter is enabled, the converter will be shut do wn and will attempt to restart after 2 seconds. in case of startup into short circuit, internal log ic detects short circuit condition and shuts down converter typical 5 msec after condition is detected. the converter will attempt t o restart after 2 seconds until short circuit condition exists. output overvoltage protection (ovp) the converter will shut down if the output voltage across +out (pins 5 and 6) and Cout (pins 8 and 9) exceeds the threshold of the ovp circuitry. the ovp circuitry contains its o wn reference, independent of the output voltage regulation loop. once the converter has shut down, it will attempt to restart every 2 seconds until the ovp condition is removed. note that ovp threshold is set for nominal output v oltage and not trimmed output voltage value or remote sense voltag e. overtemperature protection (otp) the icf converters have non-latching overtemperatur e protection. it will shut down and disable the output if tempera ture at the center of the base plate exceeds a threshold of 115 c (typical). measured with icf converter soldered to 5 x 3.5 x 0.07 4 layers/ 2 oz cooper fr4 pcb. the converter will automatically restart when the b ase temperature has decreased by approximately 20c.
