I used TI's workbench to design a simple 24 to 12V @ 6A. I have it built in a PCB board, but I started doing some power measurements and notice the output voltage ripple is quite high at loads bigger than 1A. According to the WB design, ripple should be around 100mV p-p, but I'm seeing ripples as high as 700mV p-p. Can anyone help?
This is my schematic that I got from TI"s WB:
This is my PCB Layout
And this is what I am seeing on the scope:
