MB39C603

MB39C603 Phase Dimmable PSR LED Driver IC for LED Lighting 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-component count. It is most suitable for the general lighting applications, for example replacement of commercial 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  Dimming curve based...
