MAX17631 - Synchronous Step-Down DC-DC Converter

Description

The MAX17631 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 1.5A current.

The MAX17631 is available in three variants, MAX17631A, MAX17631B and MAX17631C.

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 lightload conditions. The MAX17631 offers a low minimum ontime that allows high switching frequencies and a smaller solution size. The feedback-voltage regulation accuracy over -40°C to +125°C for the MAX17631A/MAX17631B/MAX17631C is ±1.2%. The device is available in.

MAX17631 EVALUATION KIT AVAILABLE 4.5V to 36V, 1.5A, High-Efficiency, Synchronous Step-Down DC-DC Converter General Description The MAX17631 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 1.5A current. The MAX17631 is available in three variants, MAX17631A, MAX17631B and MAX17631C. The MAX17631A and MAX17631B are fixed 3.3V and fixed 5V output parts, respectively. The MAX17631C 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.
