Description

The CS5132 is a dual output CPU power supply controller. It contains a synchronous dual NFET buck controller utilizing the V2TM control method to achieve the fastest possible transient response and best overall regulation. The CS5132 also contains a second nonsynchronous NFET buck controller.
