Texas Instruments UCC28881 | Demoboard TIDA-00776

Description

The TIDA-00776 design is a 350-W cost competitive power factor regulator converter designed for refrigerators and other appliances applications. This reference design is a Continuous-Conduction-Mode (CCM) boost converter that uses TI’s UCC28180 PFC controller and has all the necessary built-in protections. The hardware is designed and tested to pass the current harmonic requirement of IEC61000-3-2 (2014) for household appliances.
