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.

Features

? Provides 5 ACPI-Controlled Voltages

- 5VDUAL USB/Keyboard/Mouse (Active/Sleep)

- 3.3VDUAL/3.3VSB PCI/Auxiliary/LAN (Active/Sleep)

- 2.5VMEM RDRAM (Active/Sleep)

- 3.3VMEM SDRAM (Active/Sleep)

- 2.5VCLK Clock/Processor Terminations (Active Only)

? Excellent Output Voltage Regulation

- 3.3VDUAL/3.3VSB Output: ±2.0 Over Temperature; Sleep State Only

- 2.5VMEM and 3.3VMEM Output: ±2.0 Over Temperature; Both Operational States (3.3VMEM in Sleep Only)

- 2.5VCLK Output: ±2.0 Over Temperature

? Small Size

- Very Low External Component Count

? Dual Memory Voltage Support Via MSEL Pin

- 2.5V for RDRAM Memory
