For my banch power supply (variable, IC Lm2576, input 40vdc, output 2v to 37v, Frequency is 52kHz. Current out 20mA to 3A (3.65A max)) I wound an inductor of 330uf. The core is iron powder toroidal T94-26 (OD-23.9mm, ID-14.2mm, H-7.92). I wound 74 turns of 2 strands of wire (Dia- 0.457mm).
I need to know the right wire size (diameter & no. of strands) for the inductor.
