Lzc8650c Ic Datasheet Pdf Better Portable (2024)

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. Key Features and Specifications

Achieves accurate LED current control without secondary-side feedback, simplifying the design of AC/DC flyback converters. lzc8650c ic datasheet pdf better

Operates in QR mode (valley switching) to minimize MOSFET switching losses and improve overall efficiency. Operates in QR mode (valley switching) to minimize

The LZC8650C belongs to a family of LED driver ICs (like the DIO8650C and LZC8620 ) that focus on efficiency and power quality. VDD (Pin 6): Power supply pin for the IC

Gate driver output to control the external power MOSFET. VDD (Pin 6): Power supply pin for the IC.

Used in flicker-free lighting designs due to its stable PFC control.

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.
