OB6683 - High Performance TM PFC/QR Combo Controller
OB6683 integrates a transition mode power factor correction (TM PFC) controller and a QuasiResonant (QR) controller in one chip.
The PFC controller provides a cost effective solution for optimizing the power factor.
The QR controller provides higher efficiency and lower EMI compared to conventional
OB6683 Features
* 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, OB66
