The MAX17632 is a high-efficiency, high-voltage, synchronous step-down DC-DC converter with integrated MOSFETs operating over an input-voltage range of 4.5V to 36V. It can deliver up to 2A current. The MAX17632 is available in three variants, MAX17632A, MAX17632B, and MAX17632C. The MAX17632A and MAX17632B are fixed 3.3V and fixed 5V output parts, respectively. The MAX17632C is an adjustable output voltage (from 0.9V up to 90% of VIN) part. Built-in compensation across the output-voltage range eliminates the need for external compensation components.The MAX17632 features peak-current-mode control architecture. The device can be operated in the forced pulse-width modulation (PWM), or pulse-frequency modulation (PFM), or discontinuous-conduction mode (DCM) to enable high efficiency under full-load and light-load conditions. The MAX17632 offers a low minimum on-time that allows high switching frequencies and a smaller solution size.The feedback-voltage regulation accuracy over -40°C to +125°C for the MAX17632A/MAX17632B/MAX17632C is ±1.2%.The device is available in a 16-pin (3mm x 3mm) TQFN package. Simulation models are available.ApplicationsBase Station Power SuppliesDistributed Supply RegulationGeneral-Purpose Point-of-LoadHigh Voltage Single-Board SystemsIndustrial Control Power SuppliesWall Transformer Regulation
