I am modulating power to a pump (power on and off) and when I am doing this I am seeing dips in the input voltage to my power regulators (Vin) on other parts of my board.
What is the best approach to guarantee that my Vin won't dip during these current transients caused by my pump? I added some larger input and output capacitors that helped a little but didn't fix the problem. Should I be adding an inductor/choke to help with this? How should I be calculating what type of inductor to use?
Thanks in advance for any info!
