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
