 Integrated two-stage combo controller allowing for reduced number of external components, optimized Bill

of Materials (BOM) and form factor.

 PFC controller with Critical Conduction Mode (CrCM) and Discontinuous Conduction Mode (DCM).

 Resonant HB controller with fixed or variable switching frequency control.

 Maximum 500 kHz HB switching frequency and soft-start frequency up to 1.3 MHz.

 Resonant HB burst mode (BM) ensures power limitation and low standby power of less than 300 mW.

 Supports universal AC input voltage.

 Supports excellent system efficiency.

 THD optimization ensuring low harmonic distortion down to 30 percent nominal load.
