Part Number: LM5069
Other Parts Discussed in Thread: LM5050-2, LM5050-1

Can lm5069 be used as redundant power supply? Is there a reference circuit? What is the difference between lm5050-1, lm5050-2 and lm5069?

Hi Ping,

You would need reverse current blocking feature to support redundant power circuit configuration. ORing controller like LM5050-x along with LM5069 would be able to support your requirement. This is presented in https://www.ti.com/lit/ug/tidu415/tidu415.pdf

Please share your system specifications voltage, current, application use case details to suggest other options.

Best Regards,

Rakesh
