The ESOP-8 package has a thermal pad underneath. If this pad is not soldered to a large copper area (with thermal vias to an inner ground plane), the IC will overheat at currents above 800mA. The datasheet specifies the minimum pad size and via pattern. 2 FB : Supply voltage input with built-in

Engineers looking to download the verified datasheet document can locate the complete documentation via official chip components repositories. Ensure you reference the correct document revisions (e.g., Preliminary V1.1 or higher) to accurately match the resistor-divider ratios for both the input OVP network and the NTC thermal mapping characteristics.

The is a high-performance, single-stage Power Factor Correction (PFC) and primary-side regulation (PSR) LED driver IC, typically used in isolated and non-isolated flyback power converters. It is designed to achieve a high power factor ( >0.95is greater than 0.95

When the output terminal is directly shorted, the auxiliary winding voltage drops below the functional threshold. The IC drops into hiccup mode, continuously attempting a safe, low-power restart until the physical short is removed.
