Lzc8650c Ic Datasheet Pdf !!link!! Jun 2026
The is a highly efficient, single-stage Primary-Side Regulation (PSR) and Power Factor Correction (PFC) controller designed for offline AC/DC flyback converter LED lighting systems. By eliminating the need for secondary-side optocouplers and feedback circuitry, it simplifies circuit architecture, reduces BOM (Bill of Materials) costs, and delivers optimal constant current control. Core Overview and Architecture
, the IC ceases switching execution, allowing the system to cool down and prevent catastrophic catastrophic damage. 7. PCB Layout Design Considerations
In a standard flyback or buck-boost configuration, the LZC8650C works on the primary side of the power transformer. lzc8650c ic datasheet pdf
rated at 130°C) to withstand rugged operational conditions.
According to preliminary datasheet data from TaoIC , the LZC8650C operates within the following parameters: Typical Value Range/Limit 18.1V – 21.5V (Turn-on) VDD Over-Voltage Protection Startup Current Low standby power Operating Current MOSFET Drive Voltage Internal clamp Junction Temperature -40°C to 125°C (Recommended) Pinout Configuration (8-Pin Package) According to preliminary datasheet data from TaoIC ,
Stresses exceeding these ratings may cause permanent damage to the device.
Multiplier AC line sensing input. Connects to the rectified bulk voltage through a resistor divider to shape the input current for high PF. CS CS Built-in over-voltage (OVP)
Built-in over-voltage (OVP), short-circuit, and over-temperature protection (OTP). 📍 Pinout Configuration (8-Pin SOP)
Operates in QR switching mode to significantly reduce MOSFET switching losses and minimize electromagnetic interference (EMI).
Wide universal AC input, typically 85V to 300V AC. Package Type: Available in 8-pin SOIC (SOP-8) packages.
