OB2710
DESCRIPTION
85KHz minimum clamping frequency in CCM
OB2710 is a highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyback converter applications. At normal load condition, it operates in fixed frequency mode. When the loading goes low, it operates in PFM mode for high power conversion efficiency. When the load is very small, the IC mode @ Heavy Load in low line voltage Valley switching operation @ Green mode Burst Mode @ Light Load & No Load
- Frequency shuffling for EMI
- Extended burst mode control for improved efficiency and low standby power design
- Audio noise free operation operates in ‘Extended Burst Mode’ to minimize the
- Adjust Vth_oc pensation through CS pin, standby power loss. As a result, high conversion the pensate value can be regulated by the efficiency can be achieved in the whole loading resister series with CS pin. range. VCC low startup current and low operating current contribute...
