This reference design uses a UCC28742 flyback controller and an ATL432LI shunt reference to produce an isolated 24-V output capable of 0.625 A from an 85-V to 480-Vac input. All components are placed on one side of the board to reduce complexity and cost. The design can achieve 80% efficiency across various input conditions.
- Compact size (2 x 3.31") minimizes solution size areaSingle-side assembly and 2-layer PCB for reduced manufacturing costsLow noise output of less than 100-mV peak-to-peak voltage ripple for sensitive loads"
