PMP23377: How to use LM51770 instead of LM5177

Part Number: PMP23377
Other Parts Discussed in Thread: LM51770, LM5177,

Tool/software:

Hi all,

My customer is considering using LM51770 between battery and motor driver in the following configuration.

Vin=48~56V(Vbattery)

Vou=48V

Iout=20A

I found PMP23377 to refer to reference design. I would suggest this, but LM5177 is used.

1) Can LM51770 be used instead of LM5177?

2) Are there any other devices or reference designs you would recommend for the above configuration?

Best Regards,

Ryusuke

    Hi Fukunaga San,

        LM51770 could be pin to pin compatible with LM5177. So, you can just replace LM5177 to LM51770 without any additional process. About the other parts. I think LM51770 is good enough for customer requests.

    Regards,
