LM61460-Q1: Reference schematic for parallel application

Frank QIN

Part Number: LM61460-Q1
Other Parts Discussed in Thread: LM61460

Hi Team,

Can we share a application reference schematic of LM61460-Q1 in parallel?

We have a platform that develop with LM61460. For low end, 1pc of 61460 as 6A needed. For high end, 2pcs of 61460 as 12A output. We had a discussion, that using 61460(or 61480) in parallel would be the best solution. So any kinds of guide of parallel application can assist our design.

Thanks!

Best,

Frank

Hi Frank,

Here is a link that you can read and reference how you can run two buck regulators in parallel.

Hi Ben,

Thanks! While it is buck controller, is converter the same right?

And there is a voltage comparator in the note, is that necessary?

Thanks,

Frank

Hi Frank,

Come to think about it, I don't think you can use two LM61460 in parallel mode because both ICs need to current share. In the document I shared, the devices had a "COMP" pin for current sharing and also both parts had SNYCIN and SYNCOUT so you can operate in different phases.
