SLUSBQ5D – NOVEMBER 2013 – REVISED JULY 2016 UCC28180 Programmable Frequency, Continuous Conduction Mode (CCM), Boost Power
Factor Correction (PFC) Controller
1 Features 3 Description The UCC28180 is a flexible and easy-to-use, 8-pin,
active Power-Factor Correction (PFC) controller that
operates under Continuous Conduction Mode (CCM)
to achieve high Power Factor, low current distortion
and excellent voltage regulation of boost preregulators in AC -DC front-ends. The controller is
suitable for universal AC input systems operating in
100-W to few-kW range with the switching frequency
programmable between 18 kHz to 250 kHz, to
conveniently support both power MOSFET and IGBT
switches. An integrated 1.5-A and 2-A (SRC-SNK)
peak gate drive output, clamped internally at 15.2 V
(typical), enables fast turn-on, turn-off, and easy
management of the external power switch without the
need for buffer circuits. 1 8-Pin Solution (No AC Line Sensing Needed)
