Description

The MAX17544 high-efficiency, high-voltage, synchronousstep-down DC-DC converter with integrated MOSFETsoperates over 4.5V to 42V input. The converter can deliverup to 3.5A and generates output voltages from 0.9V up to0.9 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. Thedevice can be operated in pulse-width modulation (PWM),pulse-frequency modulation (PFM), or discontinuousconduction mode (DCM) control schemes.The device is available in a 20-pin (5mm x 5mm) TQFNpackage. Simulation models are available.ApplicationsBase Station Power SupplyDistributed Supply RegulationGeneral-Purpose Point-of-LoadHigh-Voltage Single-Board SystemsIndustrial Power Supplies
