OB2203 Quasi-Resonant Flyback PWM Controller

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 starting at 150KHz, the maximum switching frequency is i.

OB2203 Features

* Multi-Mode Operation

* Quasi-Resonant Operation at Normal Loading

* Pulse Frequency Modulation (PFM) Operation at Light Load

* Burst Mode at No Load

* Direct Control of the Power Supply of PFC Controller for Improved Standby Power at No/Light Load

* 40KHz Minimum Frequency
