HT7L5600 - Primary side regulation off line LED driver

Description

The HT7L5600 is a single-stage, isolated, primaryside offline LED lighting controller that achieves a high power factor.

Features

  • Small outline SOT23-6 package.
  • Primary-side current sensing and regulation with- out an opto-coupler.
  • Wide AC input range.
  • from 85VAC to 265VAC.
  • High Power Factor of >0.9 without additional circuitry.
  • Accurate constant current (< ±3%).
  • Low start-up current which reduces power dissipation.
  • Full protection functions for enhanced safety:.
  • Gate driver output voltage clamp.
  • VCC over vol.
