L6911E概述

采用同步整流5位可编程降压控制器 5-Bit programmable step down controller with synchronous rectification

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

■ Operating supply IC voltage from 5V to 12V buses

■ 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 RdsON

■ 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
