I am using a TL5001 to step down ~20V to 5V, datasheet here: https://www.electro-tech-online.com/custompdfs/2006/06/tl5001a.pdf
Here is the circuit I am using:
**broken link removed**
For some reason, this circuit just plain doesn't work at all. And I mean no part of it works. I was trying it on a breadboard and it wouldnt work, so I actually bought a general pc board and soldered all the components on and I get the same results. Nothing works.
My output switching frequency should be around 100khz and should look like a triangle wave that should have a min at 0.7 and a max at 1.3, but instead the output looks like this:
**broken link removed**
When I measure the output voltage (5V) I just get 20V (same as the input voltage). I have no idea what I am doing wrong and could use some help. I have worked with other PWM controllers and I have at least be able to get the switch output to work fine (even on a breadboard), nothing is working with this IC.
Also, I ordered 3 TL5001's and they all work the same way, so I doubt I got a defective copy.
