MAX17545 - Maxim Integrated

MAX17545 Synchronous Step-Down DC-DC Converter

The MAX17545 high-efficiency, high-voltage, synchronous step-down DC-DC converter with integrated MOSFETs operates over 4.5V to 42V input. The converter can deliver up to 1.7A and generates output voltages from 0.9V up to 0.9 x VIN. The feedback (FB) voltage is accurate to within ±1.1% over -40°C to +125°C. The MAX17545 uses peak-current-mode control. The de.
