ACPI Regulator/Controller for Dual Channel DDR Memory Systems

The ISL6537 provides a complete ACPI compliant power

solution for up to 4 DIMM dual channel DDR/DDR2 Memory

Features

• Generates 4 Regulated Voltages

systems. Included are both a synchronous buck controller to

supply V during S0/S1 and S3 states. During S0/S1

• ACPI Compliant Sleep State Control

GMCH and CPU V termination voltage regulation.

• Glitch-free Transitions During State Changes

The switching PWM controller drives two N-Channel

MOSFETs in a synchronous-rectified buck converter

topology. The synchronous buck converter uses voltage-

mode control with fast transient response. The switching

regulator provides a maximum static regulation tolerance of

2% over line, load, and temperature ranges. The output is

user-adjustable by means of external resistors down to 0.8V.

• PWM Controller Drives Low Cost N-Channel MOSFETs

• 250kHz Constant Frequency Operation

• Tight Output Voltage Regulation

- All Outputs: 2% Over Temperature

• Fully-Adjustable Outputs with Wide Voltage Range: Down

to 0.8V supports DDR and DDR2 Specifications

An integrated soft-start feature brings all outputs into

regulation in a controlled manner when returning to S0/S1

state from any sleep state. During S0 the VIDPGD signal

• Simple Single-Loop Voltage-Mode PWM Control Design

• Fast PWM Converter Transient Response

• Under and Overvoltage Monitoring on All Outputs

• OCP on the Switching Regulator

indicates that the GMCH and CPU V termination voltage

is within spec and operational.

Each output is monitored for undervoltage events. The

switching regulator also has overvoltage and overcurrent

protection. Thermal shutdown is integrated.
