Used in flicker-free lighting designs due to its stable PFC control.
Feedback pin for zero-crossing detection (ZCD) and over-voltage protection (OVP). It senses reflected voltage from the auxiliary winding.
Current sense pin. It monitors the voltage across a sense resistor connected to the primary MOSFET's source for cycle-by-cycle current limiting. GND (Pin 4): Power and signal ground.
Works effectively across the 85V to 305V AC range, making it suitable for global markets.
Features an integrated temperature foldback (OTP) function that automatically reduces output current as the temperature rises, preventing catastrophic failure. Typical Value / Range Supply Voltage (VDD) 9.5V to 27V (Operating range) Startup Current ~10 µA (Extremely low for quick start) Gate Drive Clamp 16V (Internal protection for external MOSFET) Operating Temperature -40°C to 125°C Pin Configuration and Functions The LZC8650C is commonly available in a SOP-8 package.
Loop compensation for constant current and voltage regulation. Connects to an external RC network to ground.
For detailed design and calculation, refer to the LZC8650C Datasheet for the latest electrical characteristics and recommended operating conditions.
The LZC8650C belongs to a family of LED driver ICs (like the DIO8650C and LZC8620 ) that focus on efficiency and power quality.
