This application report describes use of UCC28810 in a single-stage 70-W streetlight LED driver in AC/DC flyback topology with fixed-frequency and constant on-time switching, to achieve power factor >0.9 and current THD <10%.
In this paper, the combined dimming solution (PWM and 1- to 10-V analog) based on the UCC28810/11 device is provided to meet today’s wider dimming range specification for the LED ceiling lamp application.
