FAN5063
ACPI Dual Switch Controller
www.fairchildsemi.com
Features
• 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
Description
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
