Over-temperature protection configuration. Sets the thermal threshold using an external NTC resistor to initiate current foldback. OVP AC Line voltage over-voltage protection input point. Core Operational Features

is a highly integrated, high-performance LED driver controller designed for offline LED lighting applications . It is engineered by Lozen Technology (and closely related to the DIO8650C) to offer high power factor (PFC), excellent current accuracy, and simplified design for LED driving systems. By utilizing primary-side feedback, the IC eliminates the need for optocouplers and secondary feedback components, reducing costs and increasing system reliability. Feedback pin used to regulate output current via

The MULT pin (Pin 3) samples the rectified sinusoidal input voltage waveform. The internal multiplier forces the peak primary current envelope to track the input voltage waveform perfectly, resulting in a high power factor and ultra-low Total Harmonic Distortion (THD). Troubleshooting and Design Considerations

Based on equivalent series controllers like the DIO8650C , the typical electrical limits include: Typically 9.5V9.5 cap V to 27V27 cap V (Absolute maximum up to 33V33 cap V ). Operating Temperature: to ambient. Power Dissipation: Approximately 0.6W0.6 cap W for SOT23-6 and 1.1W1.1 cap W for SOIC-8 at . Core Functionalities senses reflected voltage from auxiliary winding.
