MB39C605 Datasheet Phase Dimmable PSR LED Driver IC

Manufacturer: Cypress (now Infineon)

General 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.

Overview

MB39C605 Phase Dimmable PSR LED Driver IC for LED Lighting.

Key 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.
