FN4871, Multiple Linear Power Controller with ACPI Control Interface

3V3 (Pin 7) Connect this pin to the ATX 3.3V output.

This pin provides the output current for the 2V5CLK pin, and is monitored for power quality.

event, this pin is used to report the fault condition by being pulled to 5VSB.

SS (Pin 16) Connect this pin to a small ceramic capacitor (no less than 5

HIP6502B TM Data Sheet May 2000 File Number 4871 Multiple Linear Power Controller with ACPI Control Interface The HIP6502B complements either an HIP6020 or an HIP6021 in ACPI-compliant designs for microprocessor and computer applications.

The IC integrates four linear controllers/regulators, switching, monitoring and control functions into a 20-pin SOIC package.

One linear controller generates the 3.3VDUAL/3.3VSB voltage plane from the ATX supply’s 5VSB output, powering the south bridge and
