I'm using this circuit design:
"https://www.eevblog.com/forum/proje...onverter/?action=dlattach;attach=294867;image"
action=dlattach;attach=294867;image"
But I changed some values:
R1:220 ohms
R3:470 ohms
C1:470PF
M1: TIP41C.
When I turn the converter on and connect a 500MA Load,
The output voltage significantly drops from 5.6V to 4.6V, And
there is voltage drop across my inductor(???)
My question is; Is there any fault on my side? I used every
other thing of same value except the components above.
Is my inductor saturating, Because I'm getting 0.07v drop
across it, which is odd.
Any ideas what is going on?
(By the way, I'm stepping up 3.7v to 5V for Led strip. I like
discrete.)
