The UCC28019DR from Texas Instruments is an 8-pin active Power Factor Correction (PFC) controller designed for boost topology operating in Continuous Conduction Mode (CCM). This controller is suitable for systems ranging from 100 W to over 2 kW and supports a wide-range universal AC line input.
Key electrical specifications include a fixed operating frequency of 65kHz and a maximum duty cycle of 97%. It provides essential protection features such as output over/under-voltage protection, input brown-out protection, and cycle-by-cycle peak current limiting. The device also includes open loop detection and a low-power user-controlled standby mode.
Packaged in an 8-SOIC surface mount package, the UCC28019DR operates within a temperature range of -40°C to 125°C. Its design aims to reduce external components with an 8-pin solution without sensing line voltage.
Applications for the UCC28019DR include CCM Boost Power Factor Correction in power converters, server and desktop power supplies, telecom rectifiers, industrial electronics, and home electronics.
