The design of a Flyback Converter Based on LD7550B

The single-ended flyback converter is a widely used topology method,and the flyback converter based on LD7550B has many advantages.The design of converter is very important for switch power supply design.Through the design of a 10 W power converter,we can basicaly learn the useage of LD7550B.The PCB design of switch power supply is important to the power supply performance.Actually measured wave form of flyback converter can be taken as a reference for design of similar switch power supplies.
