ISL6440A Datasheet | Intersil

Data Sheet October 2001 File Number 9041 Advanced PWM and Triple Linear Power Controller for Gateway Applications The ISL6440A provides the power control and protection for four output voltages required by microprocessors used in high-performance, graphics-intensive gateway applications. The IC integrates a voltage-mode PWM controller and three linear controllers, as well as the monitoring and protection functions into a 28 lead SOIC package. The synchronous rectified buck converter includes an Intel®patible, TTL five-input, digital-to-analog converter (DAC) that adjusts the core PWM output voltage from 1.3VDC to 2.05VDC in 0.05V steps and from 2.1V DC to 3.5VDC in 0.1V...
