Description

General part information

MAX17575 Series

The MAX17575 high-efficiency, high-voltage, synchronous step-down DC-DC converter with integrated MOSFETs operates over a 4.5V to 60V input. The converter can deliver up to 1.5A and generates output voltages from 0.9V up to 0.9 x VIN. The feedback (FB) voltage is accurate to within ±1.2% over -40°C to +125°C. Built-in compensation across the output-voltage range eliminates the need for external components. The MAX17575 features peak-current-mode control architecture and operates in fixed frequency forced PWM mode. The MAX17575 offers a low minimum on-time that allows high switching frequencies and a smaller solution size.The device is available in a 12-pin (3mm × 3mm) TDFN package. Simulation models are available.ApplicationsBase Station Power SuppliesDistributed Supply RegulationGeneral-Purpose Point-of-LoadHigh-Voltage, Single-Board SystemsIndustrial Control Power SuppliesWall Transformer Regulation
