Overview

PROGRAMMABLE SYNCHRONOUS DC/DC HYSTERETIC CONTROLLER WITH VRM 9.
0 VID RANGE PRELIMINARY - August 7, 2000 SC1155 DESCRIPTION The SC1155 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 SC1155 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.
Inhibit, under-voltage lockout and soft-start functions are included for controlled power-up.
SC1155 features include an integrated 5 bit D/A converter, temperatur...
