HIP6500 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. SS (Pin 16) Connect this pin to a small ceramic capacitor (no less than 5nF; 0.1µF recommended). The internal soft-start (SS) current source along with the external capacitor creates a voltage ramp used to control.

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 External Component Count
• Selectable Memory Output Voltage Via FAULT/MSEL Pin - 2.5V for RDRAM Memory - 3.3V for SDRAM Memory .
