The FAN5067 is an ACPI Switch Controller for Pentium IV Platforms. It is controlled by PWROK, SLP_S3 and SLP_S5, and provides 3.3V or 5V Dual and VADJ Dual output for SDRAM or DDR with 200mA minimum base current for an external NPN transistor. An on-board precision low TC reference achieves tight tolerance voltage regulation without expensive external components. The FAN5067 also offers integrated Current Limiting that protects each output, and softstart for the linear regulators. The FAN5067 is available in a 16 pin SOIC.
