The UCC28742DBVT from Texas Instruments is a high-efficiency, offline flyback controller designed for AC-to-DC power supplies. This integrated circuit features secondary-side regulation, enabling up to 1% output regulation accuracy. It operates with a maximum switching frequency of 80kHz and supports a maximum duty cycle of 99%.
Key features include current limiting, overvoltage protection, and short-circuit protection, along with DCM and valley switching operation for enhanced efficiency. The device is housed in a compact SOT-23-6 package, suitable for surface mount applications. Its input voltage range is between 9V and 35V, with an operating temperature range of -40°C to 125°C.
This controller is designed for applications requiring efficient power conversion, such as consumer electronics and industrial power supplies. The secondary-side regulation and opto-coupled feedback contribute to precise output control, while features like frequency dithering aid in EMI compliance.
