MB39C603 Datasheet (Cypress) - Phase Dimmable PSR LED Driver IC

MB39C603, Phase Dimmable PSR LED Driver IC

MB39C603 is a Primary Side Regulation (PSR) LED driver IC for LED lighting.

Using the information of the primary peak current and the transformer-energy-zero time, it is able to deliver a well regulated current to the secondary side without using an opto-coupler in an isolated flyback topology.
