MT7963 - Dual Winding PSR AC-DC LED Driver

Description

MT7963 is a PWM controller for AC-DC LED lighting.

With primary side sensing and regulation technology, no secondary side feedback circuit is needed.

Further, the loop compensation components are also eliminated while maintaining system stability.

Features

  • Build in 650V power MOSFET.
  • No auxiliary winding needed.
  • Supporting 85V to 265V AC line voltage range.
  • Primary side sensing and regulation, no need of secondary side feedback.
  • High precision constant LED current (+/-5%).
  • Cycle-by-cycle peak current control.
  • LED short-circuit protection.
  • VDD under voltage lock-out protection.
  • Over temperature protection.
  • Available in SOP8 package.
