Design UCC28881
SLUSC36B – NOVEMBER 2015 – REVISED JANUARY 2016 UCC28881 700-V, 225-mA Low Quiescent Current Off-Line Converter
1 Features 3 Description The UCC28881 integrates the controller and a 14-О©,
700-V power MOSFET into one monolithic device.
The device also integrates a high-voltage current
source, enabling start up and operation directly from
the rectified mains voltage. UCC28881 is the same
family device of UCC28880, with higher current
handling capability. 1 Integrated 14-О©, 700-V Power MOSFET
