OB6683 integrates a transition mode power factor correction (TM PFC) controller and a QuasiResonant (QR) controller in one chip.

many built-in green functions to optimize power conversion efficiency at all power levels. This holds for QR operation at high power levels, as well as PFM operation at lower power levels, and ‘Extended Burst Mode’ operation at very low power or zero power (Standby) levels. At low power levels, OB6683 can turn off the PFC stage. In this way, low standby together with low system cost can be achieved. The device is also integrated many functions of protection, such as X-CAP discharge, Brownin/out.
