Description
The device is a power supply controller specifically designed to provide a high performance DC/DC conversion for high current
microprocessors. A precise 5 bit digital to analog converter (DAC) allows to adjust the output voltage from 1.050 to 1.825 with 25mV binary steps.

FEATUREs

■ Up to 1.3A gate current capability
■ TTL-compatible 5 bit programmable output compliant with VRM 8.5 : 1.050V to 1.825V with 0.025V binary steps
■ Voltage mode PWM control
■ Excellent output accuracy: ±1% over line and temperature variations
■ Very fast load transient response: from 0% to 100% Duty Cycle
■ Power good output voltage
■ Overvoltage protection and monitor
■ Overcurrent protection realized using the upper MOSFET's Rds(ON)
■ 200kHz internal oscillator
■ Oscillator externally adjustable from 50kHz to 1MHz
■ Soft start and inhibit functions

Applications
■ Power supply for advanced microprocessor core
■ Distributed power supply
