Sep 27, 1. Sep 26, 18 0. Hi Guys, I am trying to figure out from the maths of a Step-down Switching regulator. The attached image is from the data sheet 1. How the output voltage is calculated?
How would I know the peak current which this is designed.? Sep 27, 2.

Sep 27, 4. Feb 11, 5, 1, Output voltage is set by the voltage divider R1: R2 ratio, so that there is 1. So you need to change R1 to change the 10v output.
For 20v output you would have 1. Sep 27, 5. Sep 7, 2, 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 that datasgeet don’t want to waste a lot of catalog pages on.
