Primary Bias Winding
I start to design on INN3672C. In my application, I need 11V, 700mA output (+/- 100mV ripple volt is ok) and input volt will be 200V AC to 265VAC. There is no power constrain on mains input. My question is
1. what is the role of the primary bias winding ?
2. can I design without the SMPS without primary winding ? what things to be change in this case ?
Please help me to move forward.
