Intersil HIP6020ACB

降压（2），线性（LDO）（2）4Controller, Controller, Controller, 1.3V ~ 3.5V, 1A10.8V ~ 13.2V

Overview

The HIP6020A provides the power control and protection for four output voltages in high-performance, graphics intensive microprocessor and computer applications. The IC integrates two PWM controllers and two linear controllers, as well as the monitoring and protection functions into a 28-pin SOIC package. One PWM controller regulates the microprocessor core voltage with a synchronous-rectified buck converter. The second PWM controller supplies the computer system’s AGP 1.5V or 3.3V bus power with a standard buck converter. The linear controllers regulate power for the 1.5V GTL bus and the 1.8V power for the North/South Bridge core voltage and/or cache memory circuits.
