General Description

The HT7L4811 is a non-isolation buck PWM controller for LED lighting applications.

Key Features

  • Tiny package SOT23-6.
  • Non-isolation buck topology.
  • Low BOM Cost.
  • 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 voltage protection (VCC OVP).
