On-Bright Electronics OB2202
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. 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.| Part No. | OB2202 |

GENERAL DESCRIPTION
FEATURES
● 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. As a result, lower standby power consumption and higher conversion o efficiency can be achieved. B OB2202 offers comprehensive protection coverage including Cycle-by-Cycle Current Limiting, VCC Under Voltage Lockout(UVLO), Programmable to Output Over Voltage Protection(OVP), VCC Clamp, Gate Clamp, Over Load Protection(OLP), On-chip l Thermal Shutdown, Programmable Soft Start, Programmable Brownout Protection, Programmable tia Over Power Protection (OPP) Compensation, and External Latch Triggering, Max On-time Limit, etc. fiden OB2202 is offered in SOP-8 and DIP-8 packages.
● Burst Mode at No Load
● Excellent OPP Compensation
● 20KHz Minimum Frequen...
