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 onboard precision low TC reference achieves tight tolerance voltage 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.
