MB39C605
Description
MB39C605 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, MB39C605 has a built-in phase dimmable circuit and can constitute the lighting system for phase dimming. It is most suitable for the general lighting applications, for example replacement of mercial and residential incandescent lamps.
Features
- PSR topology in an isolated flyback circuit
- High efficiency (>80% : without dimmer) and low EMI by detecting transformer zero energy
- TRAIC Dimmable LED lighting
- Highly reliable protection functions
