Texas Instruments UCC28060 Single-Chip, PFC Controller
Texas Instruments' UCC28060 PFC controller achieves high-efficiency ratings in applications ranging from multi-kilowatt communication, server, and industrial systems, to digital TVs and PCs. The PFC controller device features an input filter and output capacitor current cancellation that provides reduced current ripple for higher system reliability and smaller bulk, as well as a reduced EMI filter size. The Texas Instruments UCC28060 enables the use of low-cost diodes without extensive snubber circuitry.
