The FAN5067 is an ACPI switching controller for the Pentium IV platform. It is controlled by PWROK, SLP_S3 and SLP_S5, and provides 3.3V or 5V Dual and VADJ Dual outputs for SDRAM or DDR, providing 200mA minimum base current for external NPN transistors. The on-board precision low TC reference achieves tight tolerance voltage regulation without expensive external components.

The FAN5067 also offers integrated current limiting, protection for each output, and a soft start linear regulator. The FAN5067 uses a 16-pin SOIC.The FAN5067 is a fully compatible ACPI controller IC that is used with an ATX power supply to generate 3.3V or 5V Dual for SDRAM or DDR power and integrates a host of additional protection features.
