HT7L4811 Non-isolation Buck LED Lighting Driver with Active PFC
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) ♦♦ VCC under-
voltage lockout with hysteresis (VCC UVLO) ♦♦ Output LED string over current protection ♦♦ Output LED string short protection ♦♦ Output LED string open protection ♦♦ On-chip over temperature protection (OTP)
Applications
General illumination E26/27, T5/T8 LED Lamp Other LED Lighting Applications
General Description
