The is a primary-side modulation isolated driver IC designed for efficient offline AC/DC flyback and Buck-Boost power converters, primarily used in LED lighting . It is manufactured by Lozen Technology (菱奇半导体) . Key Technical Specifications

Supports a wide input voltage range (e.g., 85–300 Vac) and provides accurate LED current control. Package Type: Available in a compact (8-pin) package. Typical Application Circuit & Pins

In a standard flyback configuration, the 8-pin layout typically includes: lzc8650c ic datasheet pdf

Detected when the FB pin voltage drops below 0.7V for a prolonged duration. The IC stops switching and attempts an auto-restart sequence.

Feedback/Compensation Pin. Connects to the auxiliary winding through a resistor divider to sense output voltage. The is a primary-side modulation isolated driver IC

Common applications include:

Proactively verify the manufacturer guidelines if planning a design change or substituting this chip with alternative single-stage controllers like the Mouser Electronics DIO8650C or equivalent PSR chips. Package Type: Available in a compact (8-pin) package

: Available in standard space-saving formats, typically an 8-pin SOIC-8 package.

Supports both isolated Flyback and non-isolated Buck-Boost circuits. Power Factor: is greater than 0.95 at 230VAC with Total Harmonic Distortion (THD) Switching Mode:

Protects the external MOSFET from over-current destruction.

Unlike standard ICs that abruptly shut off when hot, the LZC8650C uses the OTP pin connected to an NTC resistor. When the temperature hits the foldback point ( TZFcap T sub cap Z cap F end-sub
