AC/DC Auxiliary Supply Reference Design using UCC28700
Description
The PMP10937 reference design uses Buck converter to convert universal AC input voltage to a 18V/0.3A DC output with UCC28700 controller. Circuit simplicity is achieved with quasi-resonant valley-switching operation and the utilization of Buck topology. With all components placed within the dimension of 1.05 x 2.1": over 80% efficiency is achieved at full load and no load power consumption of this board is about 150mW."
