MB39C604 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. Operating in critical conduction mode, a smaller transformer is required. In addition, MB39C604 has a

built-in dimmable circuit and can constitute the lighting system for PWM dimming.

It is most suitable for the general lighting applications, for example replacement of commercial and residential incandescent lamps.
