The UCC28780DR from Texas Instruments is a high-frequency active clamp flyback controller. This device is designed for AC/DC conversion applications, operating at switching frequencies up to 1MHz.
Key features include full and partial Zero Voltage Switching (ZVS) of the primary FET with adaptive control, programmable timing for external FETs, and programmable adaptive burst control for light-load efficiency. It also incorporates input line monitoring, brownout detection, and programmable over-power protection (OPP).
Fault protections are comprehensive, including over-temperature, output over-voltage, output short-circuit, over-current, and pin fault detection. The controller supports secondary-side regulation and has an internal soft start function. It is available in a 16-SOIC package and is designed for surface mount.
This controller is suitable for applications requiring efficient and reliable AC/DC power conversion, offering advanced control features and robust protection mechanisms.
