Question: I used MAX20078 as the lamp driver, i need about 23A current, but i only can get 16A from it. What is the problem you think?
Answer: Most of such problems are caused by feedback path, you should be careful with it. Some notes as below:
1.Sense resistor should as close as to the mosfet.
2. CSP and CSN should be in parallel and stay away from noise source
3. A capacitor between CSP and CSN close the the chip is helpful.
