ACPI Regulator/Controller for
Dual Channel DDR Memory Systems
The ISL6537A 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 to
supply V DDQ during S0/S1 and S3 states. During S0/S1 state,
a fully integrated sink-source regulator generates an accurate
(V DDQ /2) high current V TT voltage without the need for a
negative supply. A buffered version of the V DDQ /2 reference is
provided as V REF . A second PWM controller, which requires
external MOSFET drivers, is available for regulation of the
GMCH Core voltage. An LDO controller is also integrated for
the CPU V TT termination voltage regulation and the DAC.
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.
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
indicates that the GMCH and CPU V TT termination voltage
is within spec and operational.
All outputs, except VDAC, have undervoltage protection.
The switching regulator also has overvoltage and
overcurrent protection. Thermal shutdown is integrated.
