FAN5063

ACPI Dual Switch Controller

Features

Description

• Implements ACPI control with PWROK, SLP_S3 and

SLP_S5

• Switch and linear regulator controller for 3.3V Dual (PCI)

• Linear regulator controller and linear regulator for VADJ

Dual output adjustable from 2.5V to 3.5V

• Break-before-Make

• Drives all N-Channel MOSFETs plus NPN

• Latched overcurrent protection for outputs

• Power-up softstarts for the linear regulators

• UVLO guarantees correct operation for all conditions

• 16 pin SOIC package

The FAN5063 is an ACPI Switch Controller for the Camino,

Whitney and Tehama Platforms. It is controlled by PWROK,

SLP_S3 and SLP_S5, and provides 3.3V Dual for PCI and

VADJ Dual output for SDRAM or RAMBUS with 200mA

minimum base current for an external NPN transistor. An on-

board precision low TC reference achieves tight tolerance volt-

age regulation without expensive external components. The

FAN5063 also offers integrated Current Limiting that protects

each output, and softstart for the linear regulators. The

FAN5063 is available in a 16 pin SOIC.

Applications

• Camino Platform ACPI Controller

• Whitney Platform ACPI Controller

• Tehama Platform ACPI Controller
