L6911C - 5 BIT PROGRAMMABLE STEP DOWN CONTROLLER

Datasheet Summary

Description

The device is a power supply controller specifically designed to provide a high performance DC/DC conversion for high current microprocessors.

Features

a 15MHz gain-bandwidth product and 10V/µsec slew rate which permits high converter bandwidth for fast transient performance. The resulting PWM duty cycle ranges from 0% to 100%. The device protects against overcurrent conditions entering in HICCUP mode. The device monitors the current by using the rDS(ON) of the upper MOSFET which eliminates the need for a current sensing resistor. The device is available in SO20 package. Oscillator The switching frequency is internally fixed to 200kHz. The inte.
