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 pensation 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...
