1-Phase Quick-PWM GPU Controller
General Description
The MAX17409 is a 1-phase Quick-PWM? step-down
VID power-supply controller for high-performance graph-
ics processors. The Quick-PWM control provides instan-
taneous 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.
The MAX17409 is intended for two different notebook
processor core applications: either bucking down the bat-
tery directly to create the core voltage, or bucking down
the +5V system supply. The single-stage conversion
method allows this device to directly step down high-volt-
age batteries for the highest possible efficiency.
Alternatively, 2-stage conversion (stepping down the +5V

A slew-rate controller allows controlled transitions
between VID codes. A thermistor-based temperature
sensor provides programmable thermal protection.
