General 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.

Overview

MB39C603 Phase Dimmable PSR LED Driver IC for LED Lighting.

Key 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.
