MAX17409 1-Phase Quick-PWM NVIDIA CPU Controller

MAX17409 Description

19-4590; Rev 0; 4/09 www.DataSheet4U.com KIT ATION EVALU E L B AVAILA 1-Phase Quick-PWM NVIDIA CPU Controller General .
The MAX17409 is a 1-phase Quick-PWM™ step-down VID power-supply controller for NVIDIA® graphics power.

MAX17409 Features

* o 1-Phase Quick-PWM Controller o ±6mV VOUT Accuracy Over Line, Load, and Temperature o o o o o o o o o o 6-Bit Graphics DAC (12.5mV LSB) Active Voltage Positioning with Adjustable Gain Accurate Droop and Current Limit Remote Output and Ground Sense Buffered 2V Reference Output for Offsets Power-Good

MAX17409 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 +5
