MAX17544ATP+ by Analog Devices

4.5V–42V, 3.5A, High-Efficiency, Synchronous Step-Down DC-DC Converter with Internal Compensation


The MAX17544 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 3.5A 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 MAX17544 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 (5mm x 5mm) TQFN package. Simulation models are available.
