ACPI Regulator/Controller for Dual

Channel DDR Memory Systems

Features

• Generates 3 Regulated Voltages

The ISL6532A provides a complete ACPI compliant power

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

systems. Included are both a synchronous buck controller

- Synchronous Buck PWM Controller with Standby LDO

- 3A Integrated Sink/Source Linear Regulator with

Accurate VDDQ/2 Divider Reference.

and integrated LDO to supply V

with high current during

DDQ

- Glitch-free Transitions During State Changes

- LDO Regulator for 1.5V Video and Core voltage

S0/S1 states and standby current during S3 state. During

S0/S1 state, a fully integrated sink-source regulator

generates an accurate (V

/2) high current V voltage

• Acpi Compliant Sleep State Control

without the need for a negative supply. A buffered version of

the V /2 reference is provided as V . An LDO

controller is also integrated for AGP core voltage regulation.

• PWM Controller Drives Low Cost N-Channel MOSFETs

• 250kHz Constant Frequency Operation

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. Both the switching

regulator and standby LDO provide 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.

• Tight Output Voltage Regulation

- All Outputs: ±2% Over-Temperature

• 5V or 3.3V Down Conversion

• Fully-Adjustable Outputs with Wide Voltage Range: Down

to 0.8V supports DDR and DDR2 Specifications

• 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

Switching memory core output between the PWM regulator

and the standby LDO during state transitions is

accomplished smoothly via the internal ACPI control

circuitry. The NCH signal provides synchronized switching of

a backfeed blocking switch during the transitions eliminating

the need to route 5V Dual to the memory supply.

• Integrated Thermal Shutdown Protection

• QFN Package Option

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 PGOOD signal

indicates V is within spec and operational.

- QFN Near Chip Scale Package Footprint; Improves

PCB Efficiency, Thinner in Profile

Each output is monitored for under and overvoltage events.

The switching regulator has overcurrent protection. Thermal

shutdown is integrated.
