For my ucc28950 design,
1) The CS voltage is always much higher than my designed DCM-CCM voltage (around two times) to transit from DCM to CCM.
2) When i increase my load, the controller would output unequal pulse width on output E and output F causing the transform voltage to be different.
Does anyone know when will the controller output different pulse width on E and F ? (not in burst mode)
Thank you
