OB2202 Quasi-Resonant Flyback PWM Controller GENERAL DESCRIPTION FEATURES OB2202 is a highly integrated Quasi-Resonant (QR) ■ Multi-Mode Operation controller optimized for high performance offline ■ Quasi-Resonant Operation at Normal Loading flyback converter applications. ■ Pulse Frequency Modulation (PFM) Operation at At normal load condition, it operates in QR mode Light Load with minimum drain voltage switching. To meet the ■ Programmable Brownout Protection and Line CISPR-22 EMI starting at 150KHz, the maximum OVP Protection switching frequency is internally limited to 130KHz. It operates in PFM mode for high power conversion a efficiency at light load condition. When the loading is very small, the IC operates in ‘Extended Burst Mode’ n to minimize the switching loss.
