This reference design provides 40W isolated 24-V and 5-V output with fly-back topology. The power supply can be powered from 90-264VAC Input. This design uses valley switching fly-back controller UCC28740 controller. The design achieves peak efficiency 86% and can support 3000uF capacitive load with startup time less than 500mS, it is a single side component placement PCB design which benefit manufacture cost.
Universal AC Input range 90Vac to 264Vac
86% peak Efficiency
Startup time < 500mS at 3000uF output capacitor full load condition
Provide AC zero crossing signal
Single side component placement PCB design
Pass EMI
