I am using ST's eDesign Suite for designing power supply. The suite helps with circuit, BOM and transformer design specs.
I contacted the transformer design firm to get my transformer designed. I gave them all the information regarding the number of turns and length of wire etc..
They are asking me the polarity of transformer and also start, end pin connection of windings.
Being an amateur in transformer designing, I am unable to find any relevant information for above query.
Need Help with that.
Here is my power supply specs
Input: 100 Vac - 265 Vac - 50 Hz - Operating Vdc [98.7 V - 374.8 V] Output Power: 14.96 W Out 1: 17 Vdc (35 mVpp ripple) - 880 mA max - 14.96 W - Regulated Switching Frequency (fsw): 60 kHz
