The UCC29910A from Texas Instruments is a Buck Power Factor Correction (PFC) controller that provides high-efficiency performance across universal line voltages. It is designed for applications requiring a high power factor, meeting standards like IEC 61000-3-2.
Based on a buck topology, this controller inherently limits inrush current, eliminating the need for additional components. It operates with a typical bus voltage of 84 V and is suitable for low-voltage downstream regulation stages. The UCC29910A incorporates AC line UVLO and a controlled soft start for fast start-up, along with advanced algorithms for enhanced light-load efficiency.
Key electrical features include average current mode, burst mode, and continuous control mode (CCM). It also supports single-phase operation and has a maximum duty cycle of 90%. The device is available in a 14-pin TSSOP (PW) package, measuring 5 mm x 6.4 mm.
This controller is well-suited for high-efficiency AC-DC adapters and low-profile, high-density power supplies.
