UCC28730 - PSR Flyback Controller

Datasheet Summary

Description

The UCC28730 isolated-flyback power supply controller provides Constant-Voltage (CV) and Constant-Current (CC) output regulation without the use of an optical coupler, and wake-up signal detection to improve transient response to large load steps.
