SC1175

Low Power Dual Synchronous DC/DC

Controller With Current Sharing Circuitry

POWER MANAGEMENT

Features

Description

The SC1175 is a versatile 2 phase, synchronous, voltage mode

PWM controller that may be used in two distinct ways. First, the

SC1175 is ideal for applications where point of use output power

exceeds any single input power budget. Alternatively, the SC1175

can be used as a dual switcher. The SC1175 features a tempera-

ture compensated voltage reference, over current protection with

50% fold-back and internal level-shifted, high-side drive circuitry.

u 300kHz fixed frequency operation

u Soft Start and Enable function

u Power Good output provided

u Over current protection with 50% fold-back

u Phase-shifted switchers minimize ripple

u High efficiency operation, >90%

u Programmable output(s) as low as 1.25V

u Industrial temperature range

In current sharing configuration, the SC1175 can produce a single

output voltage from two separate voltage sources (which can be

different voltage levels) while maintaining current sharing between

the channels. Current sharing is programmable to allow loading

each input supply as required by the application.

u SOIC 20 pin package

Two Phase, Current Sharing Controller

In dual switcher configuration, two feedback paths are provided

for independent control of the separate outputs. The device will

provide a regulated output from flexibly configured inputs (3.3V,

5V, 12V), provided 5V is present for V_CC. The two switchers are

180° out of phase to minimize input and output ripple.

u Flexible, same or separate V_IN

u Programmable current sharing

u Combined current limit with fold-back

u 2 phases operating opposed for ripple reduction

u Thermal distribution via multi-phase output

Applications

Two Independent PWM Controllers

u Graphics cards

u DDR Memory

u Peripheral add-in card

u SSTL Termination

u Dual-Phase power supply

u Power supplies requiring two outputs

u Flexible, same or separate V_IN

u Independent control for each channel

u Independent and separate current limit

u 2 phases operating opposed for ripple reduction (if same

V_INused)

Typical Application Circuit

2 Channels with Current Sharing
