LMZ14203: Parallel Operation of LMZ14203

Part Number: LMZ14203
Other Parts Discussed in Thread: LMZ23608, LM73606

Hi there,

I would like to use LMZ14203 in parallel operation for getting higher current. Is there any example of using parallel operation for this kind of converters ? Also what should I do for feedback resistors and other passives for parallel operation ?

Thanks

Hi Alikaan,

I'd like to reference you to another E2E post that poses this similar question.The quick answer is no the LMZ14203 was not designed for parallel application in mind. The alternative to this is the LMZ23608/10 power module but the limitation is the output voltage is a maximum of 6V. What is your desired output voltage?

Regards,

Jimmy

Hi Jimmy,

My output voltage is 24V. Input is 28V. Expected output current will be 6A or 8A. If I can use the regulators as a parallel, it would be fine also.

Thanks!

Hi Alikaan,

Unfortunately, the LMZ23608/10 will not be able to cover your output range.
I would recommend the LM73606 regulator instead of a module in this case. This regulator will cover 6A of output current.

You can get an evaluation board and see the datasheet for recommended components for 24V output. See page 26:

Cheers,
Denislav
