Typically achieves a Power Factor (PF) > 0.95 and Total Harmonic Distortion (THD) < 10% at 230VAC.
Thermal protection setting. Often used with an NTC resistor to set the temperature foldback point. OVP (Pin 8): Input line over-voltage protection. Application Scenarios
Achieves accurate LED current control without secondary-side feedback, simplifying the design of AC/DC flyback converters. lzc8650c ic datasheet pdf better
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.
The LZC8650C is a staple in high-quality LED driver designs, such as: Typically achieves a Power Factor (PF) > 0
Used in flicker-free lighting designs due to its stable PFC control.
Loop compensation for constant current and voltage regulation. Connects to an external RC network to ground. The LZC8650C is a staple in high-quality LED
Feedback pin for zero-crossing detection (ZCD) and over-voltage protection (OVP). It senses reflected voltage from the auxiliary winding.
