I would like to build a SMPS circuit to drop 17.5 volts to 14 volts @ 5 amps with an efficiency of 95 ish %.
can anyone recomend a good chip for this ? I'd like to understand something about SMPS. Are they more efficient at higher or lower frequenzys ? I've assumed lower as then the transistor has to switch less often but what about inductors ?
