OB2203 controller equivalent, quasi-resonant flyback pwm controller.
* Multi-Mode Operation
* Quasi-Resonant Operation at Normal Loading
* Pulse Frequency Modulation (PFM) Operation at
Light Load
* Burst Mode at No Load
At normal load condition, it operates in QR mode with minimum drain voltage switching. To meet the CISPR-22 EMI startin.
OB2203 is a highly integrated Quasi-Resonant (QR) controller optimized for high performance offline flyback converter applications. At normal load condition, it operates in QR mode with minimum drain voltage switching. To meet the CISPR-22 EMI starti.
