Plastic(UL94-V0) Short circuit protection* 1 MTBF 3500 Weight s Recommended circuit If you want to further decrease the input/output K hours ripple, an “LC” filtering network may be connected g to the input and output ends of the DC/DC 1.35 converter, see (Figure 1). *Supply voltage must be discontinued at the end of short circuit duration. L TYPICAL CHARACTERISTICS +Vo Vin Cout DC DC Cin GND 0V (Figure 1) It should also be noted that the inductance and the frequency of the “LC” filtering network should be staggered with the DC/DC frequency to avoid mutual interference. However, the capacitance of the output filter capacitor must be proper. If the Operating Temp.(oC) capacitance is too big, a startup problem might arise.
