General Description

The SC1157 is a low-cost, full featured, synchronous voltage-mode controller designed for use in single ended power supply applications where efficiency is of primary concern.

Synchronous operation allows for the elimination of heat sinks in many applications.

The SC1157 is ideal for implementing DC/DC converters needed to power advanced microprocessors such as Pentium® ll (Klamath), in both single and multiple processor configurations.

Overview

PROGRAMMABLE SYNCHRONOUS DC/DC CONTROLLER FOR ADVANCED PROCESSORS Preliminary - August 7, 2000 SC1157 TEL:805-498-2111 FAX:805-498-3804 WEB:http://www.semtech.

Key Features

  • include an integrated 4-bit VID DAC, temperature compensated voltage reference, triangle wave oscillator, current limit comparator, frequency shift over-current protection, and an internally compensated error amplifier. The SC1157 operates at a fixed 140KHz, providing an optimum compromise between efficiency, external component size, and cost.
