Feedback pin for zero-crossing detection (ZCD) and over-voltage protection (OVP). It senses reflected voltage from the auxiliary winding.

Integrated protections like Output Short-Circuit Protection and VDD Over-Voltage Protection ensure reliability in harsh environments. Gate driver output to control the external power MOSFET

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 is a high-performance, single-stage Power Factor Correction (PFC) and Primary Side Regulation (PSR) controller specifically designed for isolated offline LED lighting applications. By integrating advanced control algorithms, it eliminates the need for secondary feedback components and optocouplers, significantly reducing the overall system bill of materials (BOM) and cost.
