UCC29910APW TI Power Management IC | 14-TSSOP | PFC Controller, 18V

Product Overview

The UCC29910APW from Texas Instruments is a highly integrated, single-phase power factor correction (PFC) controller designed for medium-power AC-DC applications. It operates in transition mode (TM) with a proprietary frequency foldback technique to enhance light-load efficiency. The device is housed in a compact 14-pin TSSOP package, making it suitable for space-constrained designs. With a wide input voltage range and robust protection features, the UCC29910APW simplifies PFC stage design while meeting stringent harmonic distortion standards.
