Infineon REFICL8820LED43WJTTOBO1 REFICL8820LED43WJTTOBO1 Reference Design Board ICL8820 HPF Flyback Converter

REF_ICL8820_LED_43W_JT is a 43W reference design featuring Infineon's flyback controller ICL8820. The board is a constant voltage secondary-side regulated system and is intended to be used with a CC converter for LED lighting applications. Two-stage topologies are growing because of the convenient scalability of power on the primary side as well as of the features on the secondary side. REF_ICL8820_LED_43W_JT is designed as plug- and-play solution. As a default setup, the reference design board is assembled with a start-up circuit based on a depletion-mode MOSFET BSS126I on a very small adapter board. This setup offers the lowest standby losses. If low standby consumption is not necessary as an option, the start-up circuit can be changed to a resistive start-up. 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.

• ICL8820 provides integrated burst mode for very low stand-by power <100mW & built-in jitter function
• Power factor (PF) > 0.9 and THD < 10% across a wide load range (AC input up to 277Vrms)
• Maximum AC input voltage 90 - 305Vrms
• Critical conduction mode and quasi-resonant mode with smart valley hopping
