The HIP6500B 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.

Features

• Provides 5 ACPI-Controlled Voltages

- 5V Active/Sleep (5VDUAL)

- 3.3V Active/Sleep (3.3VDUAL)

- 2.5V/3.3V Active/Sleep (2.5/3.3VMEM)

- 3.3V Always Present (3.3VSB)

- 2.5V Clock (Active Only) (2.5VCLK)

• Excellent Output Voltage Regulation

- 3.3VDUAL Output: ±2 Over Temperature; Sleep State Only

- 2.5V/3.3VMEM Output: ±2 Over Temperature; Both Operational States (3.3V setting in sleep only)

- 2.5VCLK and 3.3VSB Output: ±2 Over Temperature

• Small Size

- Very Low External Component Count

• Selectable Memory Output Voltage Via FAULT/MSEL Pin

- 2.5V for RDRAM Memory

- 3.3V for SDRAM Memory

• Under-Voltage Monitoring of All Outputs with Centralized FAULT Reporting and Temperature Shutdown

Applications

• Motherboard Power Regulation for ACPI-Compliant Computers
