Tool/software:
Hi,
I designed a buck converter based on TPS56837RPAR.
I connected a RC servo motor as a load and after applying overload. The buck converter stopped working.
As this chip is supposed to have OVC,UVLO,OV protections
I need to know the following
- What can cause to damage the board permanently?
- What tests, i need to do to find the exact issue that causing the problem? I did tests with electronic load tester but it work there upto 8A as desire. As electronic load tester has builtin safety function so it turn off when there is some issues. I need to perform tests with real load to find the problem that causing to fried buck converter board so i can add protection for it
This is the schematic of the circuit
