The UCC28019ADR from Texas Instruments is an 8-pin active Power Factor Correction (PFC) controller designed for boost topologies operating in Continuous Conduction Mode (CCM). This controller is suitable for systems ranging from 100 W to over 2 kW, supporting a wide-range universal AC line input. It features a fixed 65-kHz operating frequency with better than ±5% accuracy at 25°C and a maximum duty cycle of 98% (typ.).
The device utilizes average current mode control for low-distortion wave shaping of the input current without requiring input line sensing, which helps reduce external component count. It includes numerous system-level protection features such as output over/undervoltage protection, input brown-out protection, cycle-by-cycle peak current limiting, and open loop detection. The UCC28019ADR also offers a low-power user-controlled standby mode.
Packaged in an 8-SOIC (0.154", 3.90mm Width) surface-mount package, the UCC28019ADR operates within a temperature range of -40°C to 125°C. Its wide-range universal AC input voltage capability and robust protection features make it a versatile choice for various power supply designs.
