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
