Product Details

The MAX17572 high-efficiency, high-voltage, synchronous step-down DC-DC converter with integrated MOSFETs operates over a 4.5V to 60V input. The converter can deliver up to 1A and generates output voltages from 0.9V up to 0.9 x VIN. The feedback (FB) voltage is accurate to within ±1.2% over -40°C to +125°C. The MAX17572 uses peak current-mode control.

The device is available in a 12-pin (3mm x 3mm) TDFN package. Simulation models are available.
