com KIT ATION EVALU E L B AVAILA 1-Phase Quick-PWM NVIDIA CPU Controller General Description The MAX17409 is a 1-phase Quick-PWM™ step-down VID power-supply controller for NVIDIA® graphics power.
The Quick-PWM control provides instantaneous response to fast-load current steps.
Active voltage positioning reduces power dissipation and bulk output capacitance requirements and allows ideal positioning compensation for tantalum, polymer, or ceramic bulk output capacitors.
The MAX17409 is intended for two different notebook processor core applications: either bucking down the battery 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-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 ...
