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.
MB39C603 Key Features
- PSR topology in an isolated flyback circuit -High power factor (>0.9 : without dimmer) in Single Conversion -High effici
MB39C603 Applications
- PSR topology in an isolated flyback circuit -High power factor (>0.9 : without dimmer) in Single Conversion -High efficiency (>80 % : without dimmer) and low EM
