UCC28180DR

UCC28180DR is the tape-and-reel SOIC-8 ordering code for the Texas Instruments UCC28180 power-factor-correction controller, listed as Active Production in the datasheet package option addendum (SLUSBQ5 Rev. D) with device marking U28180. It is a continuous-conduction-mode, average-current-mode controller whose switching frequency is programmable from 18 kHz to 250 kHz, whose gate driver delivers 1.5 A source and 2 A sink peak current with a 15.2 V typical internal clamp, whose maximum duty cycle is 96 % typical, and whose VCC UVLO start-up current stays below 75 µA - with no AC line sensing required. The selection point is PFC without the line-sense network: offline supplies for lighting, appliances and industrial front ends reach their harmonic limits with a smaller schematic and a smaller controller footprint than the previous generation needed. Selection advice: the programmable frequency trades inductor size against switching loss across a wide band, so fix the frequency in the design file and check the offered lot against this exact DR code - the family’s other package and grade codes are different orderables. Parameters verified against the TI UCC28180 datasheet SLUSBQ5 Rev. D (package option addendum and product parametrics).
