HIP6500 - Multiple Linear Power Controller with ACPI Control Interface

General Description

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.

Connect this pin to a small ceramic capacitor (no less than 5nF; 0.1µF recommended).

Key Features

  • Provides 5 ACPI-Controlled Voltages - 5V Active/Sleep (5VDUAL) - 3.3V Active/Sleep (3.3VDUAL) - 2.5V/3.3V Active/Sleep (2.5VMEM) - 3.3V Always Present (3.3VSB) - 2.5V Clock (Active Only) (2.5VCLK).
  • Excellent Output Voltage Regulation - 3.3VDUAL Output: ±2.0% Over Temperature; Sleep State Only - 2.5V/3.3VMEM Output: ±2.0% Over Temperature; Both Operational States (3.3V setting in sleep only) - 2.5VCLK and 3.3VSB Output: ±2.0% Over Temperature.
  • Small Size - Very Low Ext.

HIP6500 Data Sheet December 1999 File Number 4774.1 Multiple Linear Power Controller with ACPI Control Interface The HIP6500 complements either an HIP6020 or an HIP6021 in ACPI-compliant designs for microprocessor and computer applications. The IC integrates two linear controllers and two regulators, switching, monitoring and control functions into a 20-pin SOIC package. One linear controller generates the 3.3VDUAL voltage plane from the ATX supply’s 5VSB output, powering the PCI slots through an external pass transistor during sleep states (S3, S4/S5). A second transistor is used to switch in the ATX 3.3V output for operation during S0 and S1/S2 (active) operating states. The second linear controller supplies the computer system’s 2.5V/3.
