Multiple Linear Power Controller with

ACPI Control Interface

Features

• Provides 5 ACPI-Controlled Voltages

- 5V USB/Keyboard/Mouse (Active/Sleep)

The HIP6503 complements either an HIP6020 or an

HIP6021 in ACPI-compliant designs for microprocessor and

computer applications. The IC integrates four linear

controllers/regulators, switching, monitoring and control

functions into a 20 pin SOIC package. One linear controller

supply’s 5VSB output, powering the south bridge and the

PCI slots through an external pass transistor during sleep

states (S3, S4/S5). A second transistor is used to switch in

the ATX 3.3V output for operation during S0 and S1/S2

(active) operating states. A linear controllers/regulator

supplies at choice either of 2.5V or 3.3V memory power

through external pass transistors (switch for 3.3V setting) in

active states. During sleep states, integrated pass

Two internal regulators output both a dedicated, noise-free

sleep outputs) is selectable through two digital control pins,
