Part Number: LM5122
Other Parts Discussed in Thread: LM5170

hi Team,

my customer is designing a BBU that supports 48V bidirectional input and output

and it's thinking using the LM5122, may we check if that this can support four phase synchronous boost control?

or other suitable parts?

Thanks

Hi John,

The LM5122 has been in used in designs with 4 phase boost, but I have yet to see it be used in a way to support bidirectional input and output. If you need bidirectional input and output, please look at this reference design which uses the LM5170.

Thanks,

Richard
