ISL6532B

ACPI Regulator/Controller for Dual Channel DDR Memory Systems

The ISL6532B 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

and integrated LDO to supply V

DDQ

with high current during

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

Run mode, a fully integrated sink-source regulator generates

an accurate (V

DDQ

/2) high current V

voltage without the

need for a negative supply. A buffered version of the V

DDQ

reference is provided as V

REF

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 integrated 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.

Switching the 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.

An integrated soft-start feature brings V

DDQ

into regulation

in a controlled manner when returning to S0/S1 state from

S4/S5 or mechanical off states. During S0 the PGOOD

signal indicates that all supplies are within spec and

operational.

Each output is monitored for under and over-voltage events.

Current limiting is included on the V

and V

DDQ

standby

regulators. Thermal shutdown is integrated.

NOTE: Intersil Pb-free products employ special Pb-free material sets; molding

compounds/die attach materials and 100% matte tin plate termination finish, which

is compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free

products are MSL classified at Pb-free peak reflow temperatures that meet or

exceed the Pb-free requirements of IPC/JEDEC J Std-020B.
