MB39C603
Description
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. Operating in critical conduction mode, a smaller transformer is required. In addition, MB39C603 has a built-in phase dimmable circuit and can constitute flicker less lighting systems for phase dimming with low-ponent count. 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 power factor (>0.9 : without dimmer) in Single Conversion
- High efficiency (>80 % : without dimmer) and low EMI by detecting transformer zero energy
- Built-in phase dimmable circuit
