Integrated Over-Voltage Protection (OVP), Under-Voltage Protection (UVP), Over-Temperature Protection (OTP), and cycle-by-cycle current limiting.
The LZC8650C is a single-stage, high-power-factor (PF) constant-current LED driver controller. It is specifically optimized for flyback and buck-boost topologies operating in Boundary Conduction Mode (BCM). By achieving a high power factor and low Total Harmonic Distortion (THD), this IC meets the strictest global standards for energy efficiency and power quality in solid-state lighting. Target Applications : Retrofit linear fluorescent lamps.
