SC113X

Combination Switching Controller

and Low Dropout Regulator

POWER MANAGEMENT

Features

Description

The SC1131/2/3/4 incorporates a high current low

dropout linear regulator section together with a

switching voltage-mode controller. This unique combina-

tion is well suited for high current low voltage power sup-

ply applications such as the Intel Pentium^TMP55, AMD

K6 and the Cyrix M2 processors. The SC113X was de-

signed to reduce the number of components required to

design a dual power supply for multivoltage processor

applications.

u 85% typical efficiency for switching section

u Grounded tab

u 1.5, 2.5 or 3.3V @ 1% for linear section

u Thermal shutdown

u Internal short circuit protection (LDO)

u 7 pin TO-220 package

Switching Controller Section: The switching control

section is a voltage mode controller designed for high

current, low voltage power supply applications. Key

features include a temperature compensated voltage

reference, triangular oscillator and an internally

compensated transconductance error amplifier. The

switching controller operates at a fixed frequency of

200kHz, providing an optimum compromise between

size, efficiency and cost in the intended application

areas.

Applications

u Microprocessor supplies

u Modules supplies

u 1.3V to 3.5V power supplies

u Dual power supplies from 5V source

Linear Section: The linear portion is a high performance

positive voltage regulator designed for use in

applications requiring very low dropout performance

at 1.5, 3, 5 and 7.5 Amps. Additionally, the linear

section provides excellent regulation over variations due

to changes in line, load or temperature.
