UCC2540 High-Efficiency Secondary Side Synchronous PWM Controller

The UCC2540 is a secondary-side synchronous buck PWM controller for high current and low output voltage applications. It can be used either as the local secondary-side controller for isolated dc-to-dc converters using two-stage cascaded topologies or as a secondary-side post regulator (SSPR) for mul.
