Holtek Semiconductor HT7L5610
The HT7L5610 is a single-stage, isolated, primaryside offline LED lighting controller that has the benefits of high power fFEATURES
● Primary-side current sensing and regulation without an opto-coupler● Integrated 650V MOSFET
● 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
● 8-pin DIP package
APPLICATIONS
● General illumination● E26/27, T5/T8 LED Lamp
● Other LED Lighting
