L6911C 5 BIT PROGRAMMABLE STEP DOWN CONTROLLER

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 adjusting the output voltage from 1.30V to 2.05V with 50mV binary steps and from 2.10V to 3.50V with.

L6911C 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 r
