MAX17546 Datasheet

MAX17546 Synchronous Step-Down DC-DC Converter

The MAX17546 high-efficiency, high-voltage, synchronous step-down DC-DC converter with integrated high-side MOSFET operates over a 4.5V to 42V input. The converter can deliver up to 5A and generates output voltages from 0.9V up to 0.9 x VIN. The feedback (FB) voltage is accurate to within ±1.4% over.
