MAX17543/44/45 Step-Down DC-DC Converters

Maxim's MAX17543/44/45 High-Efficiency Synchronous Step-Down DC-DC Converters are a high-efficiency, high-voltage, synchronous step-down DC-DC converter with integrated MOSFETs operates over 4.5V to 42V input. The converter can deliver 1.7A, 2.5A or 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 MAX17543/44/45 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.
