Hi,
I'm trying to validate a 240W buck converter with the LM5116 without result. My first tries have been by imposing 0.35A, 0.75A and 1A5 in the outupt by a DC load, but there are no signals in the LO and HO pins. For all of these cases VOUT goes from 0V to 100mV approximately.
However, the voltage in the signals UVLO and EN are 2V6 and 23V respectively which it means that the controller should be working.
I've checked all the connexions and they looks like ok! Any idea or sugestion??
Thank u,
David
