Part Number:LM5060
Hi TI E2E,
I use LM5060 at the output of my DC/DC converter. As the load will have either a battery or a load so I want protect converter against reverse polarity. I have a similar schematic to this from figure 41 from datasheet. Output voltage about 12V. I have problem with turn on LM5060 when my coverter is working. But when I connect external supply to input LM5060 directly, it works properly. I tried to disable UVLO and OVP, change Rs and gate resistor. I do tests either with and without the output load. It very strange for me and I don't have any idea how to repair it. I have two IRFP4468 paralell because I have about 150A on the converter output. I check singnal on gate and when I have external supply signals looks good, but when I turn on my dc/dc converter I don't have any signal. What should I check? Please give me some advice. Whether it can be related to the noise coming from the dc/dc converter?
Best Regards,
Grzegorz
