OB2202
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. As a result, lower standby power consumption and higher conversion o efficiency can be achieved. B OB2202 offers prehensive protection coverage including Cycle-by-Cycle Current Limiting, VCC Under Voltage Lockout(UVLO), Programmable to Output Over Voltage...
