Dual-Phase, Quick-PWM Controller for
IMVP-6.5 CPU Core Power Supplies
General Description
The MAX17582 is a 2-/1-phase-interleaved Quick-
PWM ? step-down VID power-supply controller for
notebook CPUs. True out-of-phase operation reduces
input-ripple-current requirements and output-voltage
ripple, while easing component selection and layout dif-
ficulties. The Quick-PWM control provides instanta-
neous response to fast load-current steps. Active
voltage positioning reduces power dissipation and bulk
output capacitance requirements and allows ideal posi-
tioning compensation for tantalum, polymer, or ceramic
bulk output capacitors.
A slew-rate controller allows controlled transitions among
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. The MAX17582 includes output undervolt-
age and thermal protection. When any of these protec-
tion features detect a fault, the controller shuts down. A
voltage-regulator power-OK (PWRGD) output indicates
the output is in regulation. Additionally, the MAX17582
features true differential current sense and a phase-good
(PHASEGD) output that indicates a phase imbalance
fault condition.
The MAX17582 implements the Intel IMVP-6.5 VID code
set. The MAX17582 is available in a 6mm x 6mm,
48-pin TQFN package.
