Dual-Phase, Quick-PWM Controllers for
IMVP-6+/IMVP-6.5 CPU Core Power Supplies
General Description
Features
The MAX17021/MAX17082/MAX17482 are 2/1-phase-
interleaved Quick-PWM? step-down VID power-supply
controllers for notebook CPUs. True out-of-phase oper-
ation reduces input ripple current requirements and
output- voltage ripple, while easing component selec-
tion and layout difficulties. The Quick-PWM control pro-
vides instantaneous response to fast load-current
steps. Active voltage positioning reduces power dissi-
pation and bulk output capacitance requirements and
allows ideal positioning compensation for tantalum,
polymer, or ceramic bulk output capacitors.
A slew-rate controller allows controlled transitions between
VID codes, controlled soft-start and shutdown, and con-
trolled exit from suspend. A thermistor-based temperature
sensor provides a programmable thermal-fault output
( VRHOT ). A current monitor output (IMON) provides an
analog current output proportional to the power consumed
by the CPU (MAX17082/MAX17482 only). Output under-
voltage, overvoltage (MAX17021/MAX17082 only), and
thermal protection shut the controller down when any of
these faults are detected. A voltage-regulator power-OK
(PWRGD) output indicates the output is in regulation.
Additionally, the MAX17021/MAX17082/MAX17482 fea-
ture true differential current sense and a phase-good
(PHASEGD) output that indicates a phase imbalance
fault condition.
The MAX17021 supports the IMVP-6+ specification
while the MAX17082/MAX17482 support the IMVP-6.5
requirements. The MAX17021/MAX17082/MAX17482
are available in a 5mm x 5mm, 40-pin TQFN package.
