LM5170EVM-BIDIR: Is 12V side able to modify 24V?

Part Number: LM5170EVM-BIDIR

Hello,

I think LM5170EVM-BDIR is able to change from 12V to 24V. Is below condition no issue?

24V side: 24V 12.5A

48V side: 48V 6.3A

Best regards,

Toshihiro Watanabe

    Yes, it works it. You just need to open up OVPB setting to allow 24V operation. The EVM is set to about 20V OVP protection on the LV port. You also need to reduce R78 to 2.4kOhm to get 24V, and change R77 to 2.1k to get 48V.
