Ultra Wide Input Voltage Range AC-DC Buck Converter using UCC28910 Reference Design


Design files


The PMP9176 reference design uses Buck converter to convert ultra wide AC input voltage (50Vac to 275Vac) to a 9V/1.1W DC output with UCC28910 controller. Circuit simplicity is achieved with quasi-resonant valley-switching operation and the utilization of Buck topology.
