As BRE has datasyeet have a look at simple switchers, or look at the 78S40 data sheet Welcome to our site! The 78S40 chip is so old, it’s data sheet may have gone through some “cut downs” which is what they do with old products datassheet they don’t want to waste a lot of catalog pages on.
Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. I found this attached file on the 78S40 datasheet. Sep 27, 8. And what about C value? Quote of the day.
Just saying hello Started by MichaelaJoy Yesterday at 6: High voltage 50v step down regulator Posted by MattP in forum: To participate you need datasneet register.
Sep 27, 9. Do you already have an account? Sep 27, 6. Chippie Member Jul 8, I don’t have the formula for the cap on me. So you need to change R1 to change the 10v output.
I’ll see if I can find it.
Sep 27, 3. The L and C values are determined by Ton and Toff, which is a function of the switcher frequency, in this case the frequency is 1MHz.
If i wanted a Vout of say 20 Volts instead of the 10 what would I need to change for this to occur.
