This AC-DC LED driver controller is a single-stage PFC flyback device designed for constant-voltage output. It supports primary-side and secondary-side regulation and is intended for cost-optimized LED driver and charger designs. The device delivers power factor greater than 0.9 and total harmonic distortion below 10% across a wide load range, with integrated burst mode supporting standby power below 100 mW. It also includes an external start-up control signal and built-in jitter to simplify EMI compliance. The controller operates from 20 kHz to 150 kHz, uses critical conduction and quasi-resonant operation with smart valley hopping, and is offered in a PG-DSO-8 package.
