General Description

The MAX17410 is a 2-/1-phase interleaved Quick-

PWM™ step-down VID power-supply controller for

notebook IMVP6+ CPUs. True out-of-phase operation

reduces input ripple current requirements and output

voltage ripple while easing component selection and

layout difficulties. The Quick-PWM control scheme 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.

The MAX17410 is intended for two different CPU core

applications: either bucking down the battery directly to

create the core voltage, or bucking down the +5V sys-

tem supply. The single-stage conversion method allows

this device to directly step down high-voltage batteries

for the highest possible efficiency. Alternatively, 2-stage

conversion (stepping down the +5V system supply

instead of the battery) at higher switching frequency

provides the minimum possible physical size.

A slew-rate controller allows controlled transitions

between VID codes. A thermistor-based temperature

sensor provides programmable thermal protection. A

power monitor provides a buffered analog voltage out-

put proportional to the power delivered to the load.

The MAX17410 is available in a 48-pin, 7mm x 7mm

TQFN package.
