MAX5951 - Buck PWM Controller

General Description

The MAX5951 is a 12V pulse-width modulated (PWM), step-down, DC-DC controller.

The device operates over the input-voltage range of 8V to 16V or 5V ±10%, and provides an adjustable output from 0.8V to 5.5V.

The device delivers up to 10A of load current with excellent load-and-line regulation.

Key Features

  • include lossless valley-mode current limit, hiccup-mode output short-circuit protection, and thermal shutdown. The MAX5951 is available in a space-saving 5mm x 5mm, 32-pin thin QFN package and is specified for operation over the -40°C to +85°C extended temperature range. Refer to the MAX5950 data sheet for a pincompatible PWM controller with hot swap. Features.
  • 8V to 16V or 5V ±10% Input-Voltage Range.
  • Lossless Valley-Mode Current Sensing.
  • Output Voltage Adjustable fr.

www.DataSheet4U.com 19-0546; Rev 0; 5/06 12V/5V Input Buck PWM Controller General Description The MAX5951 is a 12V pulse-width modulated (PWM), step-down, DC-DC controller. The device operates over the input-voltage range of 8V to 16V or 5V ±10%, and provides an adjustable output from 0.8V to 5.5V. The device delivers up to 10A of load current with excellent load-and-line regulation. The MAX5951 PWM section utilizes a voltage-mode control scheme for good noise immunity and offers external compensation, allowing for maximum flexibility with a wide selection of inductor values and capacitor types. The device operates at a fixed switching frequency that is programmable from 100kHz to 1MHz and can be synchronized to an external clock signal though the SYNCIN input.
