HT7L4813 Non-isolation Buck LED Lighting Driver with Active PFC
Features
• Non-isolation buck topology • Integrated 500V
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 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
• Package: 8-pin SOP
