General Description

The SC2655 is a synchronous-buck switch-mode controller designed for use in single ended power supply applications where efficiency is the primary concern.

The controller is a hysteretic type, with a user selectable hysteresis.

The SC2655 is ideal for implementing DC/DC converters needed to power advanced microprocessors such as Pentium® llI and Athlon®, in both single and multiple processor configurations.

Overview

Programmable Synchronous DC/DC Hysteretic Controller with VRM 9.0 VID Range POWER MANAGEMENT www.DataSheet4U.

Key Features

include an integrated 5 bit D/A converter, temperature compensated voltage reference, current limit comparator, over-current protection, and an adaptive deadtime circuit to prevent shoot-through of the power MOSFET during switching transitions. Power good signaling, logic compatible shutdown, and over-voltage protection are also provided. The integrated D/A converter provides programmability of output voltage from 1.1V to 1.85V in 25mV increments. The SC2655 high side driver can be configured as.
