Abstract: ' Vcs â'η tr 2 â' Tsw â' Rcs (4) As to AP1681 control scheme, the turn off voltage Figure , voltage. From formula (4), IO can be adjusted accordingly by changing TONS/TSW if the turn ratio Nt and , start-up, after VCC voltage is higher than turn on threshold, DIM pin voltage is pulled to zero by , primary peak current control and OCP. The CS pin turn off voltage threshold is 0.5V for current loop , could be reached by adjusting fSW, turn ratio and VBUS. Usually fSW and VBUS are determined firstly BCD Semiconductor
