Dual-Phase, Quick-PWM Controller
for IMVP6+ CPU Core Power Supplies
MAX7410
General Description
Features
o Dual-/Single-Phase Interleaved Quick-PWM
Controller
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.
o Programmable Thermal-Fault Protection
o Phase Fault Output (PHASEGD)
o Drives Large Synchronous Rectifier FETs
o 40.ꢀ to 26ꢀ Battery Input Range
o Output Overvoltage and Undervoltage Protection
o Soft-Startup and Soft-Shutdown
o Integrated Boost Switches
o Low-Profile 7mm x 7mm, 48-Pin TQFN Package
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.
