1-Phase Quick-PWM GPU Controller  
MAX17409  
General Description  
Features  
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.  
o 1-Phase Quick-PWM Controller  
o ±±6m m Accuracy Over Line, Load, and  
OUT  
Te6perature  
o ±-Bit Graphics DAC (12.56m LSB)  
o Active moltage Positioning with Adjustable Gain  
o Accurate Droop and Current Li6it  
o Re6ote Output and Ground Sense  
o Buffered 2m Reference Output for Offsets  
o Power-Good Window Co6parator  
o Te6perature Co6parator  
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  
system supply instead of the battery) at higher switching  
frequency provides the minimum possible physical size.  
o Drives Large Synchronous Rectifier FETs  
o 2m to 2±m Power Input Range  
o Adjustable Switching Frequency (±00kHz 6ax)  
o Output Overvoltage and Undervoltage Protection  
o Soft-Startup and Soft-Shutdown  
A slew-rate controller allows controlled transitions  
between VID codes. A thermistor-based temperature  
sensor provides programmable thermal protection.  
o Internal Boost Diodes  
The MAX17409 is available in a 28-pin, 4mm x 4mm  
TQFN package.
