MB39C605 - Phase Dimmable PSR LED Driver IC

Datasheet Summary

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.

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  Under voltage lock out (UVLO)  Over voltage protection (OVP)  Over current prot.

MB39C605 Phase Dimmable PSR LED Driver IC for LED Lighting 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 commercial and residential incandescent lamps.
