3 Ohms is a lot of resistance for a wire. For example, 25 SWG wire with a cross sectional area of 0.2 sq mm will have a resistance of 80mOhm for 1 metre length.
Since we are expecting 1V output, 3 Ohms load will draw ~333mA for it and will satisfy the minimum load requirement. If the current is more, then the resistance is even less!
I was wondering if you could simulate to check the output voltage.
I checked the output with the 10V input. It worked well! But the problem is current is too high! I will feed uC with that and that I afraid that uC will not handle that value (50mA is the Imax for my case). Please see the attachement
What should I do to decrease that current ?
is not that output depend on Duty Cycle (Vout = Vin x D). If I want to have 5V output and 50mA current in the output, I need to use 100ohm. If I use 100ohm in the output that gives 17Voutput! That looks weird to me...I will totally lost
