Texas Instruments UCC28722DBVR | Demoboard PMP10218

Beschreibung

The UCC28722 flyback power supply controller provides isolated-output constant-voltage (CV) and constant-current (CC) output regulation without the use of an optical coupler. The device processes information from the primary power switch and an auxiliary flyback winding for precise control of output voltage and current.Dynamically-controlled operating states and a tailored modulation profile support high-efficiency operation at all load levels without sacrificing output transient response.
