Description
HT7L5600 Primary side regulation off line
LED driver with active PFC
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 voltage protection – VCC OVP ♦♦ VCC under-voltage lockout with hysteresis –
VCC UVLO ♦♦ Output LED string over current protection ♦♦ Output LED string short / open protection ♦♦ On-chip over temperature protection – OTP
Applications
General illumination E26/27, T5/T8 LED Lamp Other LED Lighting Applications
