On-Bright Electronics OB2710
OB2710 is a highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyback converter applications. 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 compensation through CS pin, standby power loss.
