MAX17543
Description
The MAX17543 high-efficiency, high-voltage, synchronous step-down DC-DC converter with integrated MOSFETs operates over a 4.5V to 42V input. The converter can deliver up to 2.5A 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 MAX17543 uses peak current-mode control. The device can be operated in the pulse-width modulation (PWM), pulse-frequency modulation (PFM), or discontinuous conduction mode (DCM) control schemes.
The device is available in a 20-pin (4mm x 4mm) TQFN package. Simulation models are available.
