Overview

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×VIN. The feedback (FB) voltage is accurate to within ±1.1% over -40℃ to +125℃. The MAX17545 uses peak-current-mode control. The device can be operated in pulse-width modulation (PWM), pulse-frequency modulation (PFM), or discontinuous conduction mode (DCM) control schemes. The device is available in a 20-pin (4mm×4mm) TQFN package. Simulation models are available.
