Description
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.
