Summary:
This wide voltage input flyback power supply uses many of the built-in features of TOPSwitch-GX to reduce component count, transformer size and overall cost. The design revolves around a TOP245P (DIP-8 package) that uses PCB copper foil to dissipate heat, eliminating heat sinks and installation costs. The output rectifier D7 also dissipates heat in the same way.
design feature
- No external heat sink required
- Efficiency is 77% (minimum) at 85 VAC input / 35 W output
- Low no-load power consumption, <0.7 W at 230 VAC
- A small number of components: a total of 37 components, excluding I / O connectors
- Stable operation with or without 10,000 μF output snubber capacitors
- Stable and powerful transformer design capable of outputting 35 W peak power
- Meets CISPR22B EMI requirements with >10 dB margin
- Ideal for class AB and class D audio amplifiers with 6-channel Dolby Digital 6 ohm speakers

High voltage slip ring is also called high voltage slip ring,high voltage resistance slip ring, high voltage collector ring, high voltage convergence ring and so on. High voltage usually refers to the alternating curred by the slip ring, and the voltage to the ground exceeds the conventional 380V AC/DC path.
