If you can provide the (SOT23-6 or SOIC-8) and manufacturer , I can help you find a link to the specific datasheet pdf. I can also help you with the schematic design or component selection for your LED driver.
In a typical flyback setup, AC main power passes through an EMI filter and a bridge rectifier. Instead of using a large electrolytic capacitor for smoothing (which degrades power factor), a small film capacitor is used.

ceramic capacitor directly next to and Pin 6 (GND) to filter out high-frequency noise injected by the internal totem-pole gate driver circuitry. lzc8650c ic datasheet pdf
Commonly available in SOT23-6 or SOIC-8 packages. 3. Pinout Description and Functionality Go to product viewer dialog for this item.
Pin 8 acts as a guard against primary AC surges. If the line voltage rises past safe operational thresholds, it cuts off the driver stage until safe operating bounds resume. Typical Application Circuit and Design Guide
Typically achieves >90% efficiency with a Power Factor >0.95 . If you can provide the (SOT23-6 or SOIC-8)
For high-reliability configurations, the primary switch is paired with high-temperature electrolytic output capacitors rated for to perfectly survive the thermal environment enabled by the chip's core current foldback features. Technical Procurement and PDF Access
The LZC8650C includes a robust suite of safety features to ensure reliable operation under fault conditions: Over-Voltage Protection (OVP):
The IC ensures that the input current follows the input voltage, creating a high power factor, essential for meeting international regulations (e.g., Energy Star, CE). 5. Typical Application Circuits Go to product viewer dialog for this item. Instead of using a large electrolytic capacitor for
