Description

General part information

MAX17630 Series

The MAX17630 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 1A current. The MAX17630 is available in three variants, MAX17630A, MAX17630B, and MAX17630C. The MAX17630A and MAX17630B are fixed 3.3V and fixed 5V output parts, respectively. The MAX17630C is an adjustable output voltage (0.9V up to 90% of VIN) part. Built-in compensation across the output-voltage range eliminates the need for external compensation components.The MAX17630 features peak-current-mode control architecture. The device can be operated in forced pulse-width modulation (PWM), pulse-frequency modulation (PFM), or discontinuous-conduction mode (DCM) to enable high efficiency under full-load and light-load conditions. The MAX17630 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 MAX17630A/MAX17630B/MAX17630C is ±1.2%.The device is available in a 16-pin (3mm x 3mm) TQFN package. Simulation models are available.ApplicationsIndustrial Control Power SuppliesGeneral-Purpose Point-of-LoadDistributed Supply RegulationBase Station Power SuppliesWall Transformer RegulationHigh Voltage Single-Board Systems
