The Infineon’s evaluation board is 43 W high power factor flyback converter with constant voltage output based on ICL8800. The board is a constant voltage (CV) secondary-side regulated (SSR) system and is intended to be used with a constant current (CC) converter for LED lighting applications. This reference design is provided with two regulation circuits. Both circuits are designed as plug-and-play solutions, but at least one has to be connected to the main board.

Best fit topology for on/off LED driver with minimum dimming levels down to 5%
Two-stage topology combines scalability with numerous features
High light quality
Cost-effective and bottom-up design
Flexibility and low BOM for many applications
