Hello Technical Team ,

We have requirement to design Multiple Output Power Supply as per attachment. I have to design it Compact and as per Automotive /MIL Grade. I have selected some Power Supply module as attached in attachment.

Please check it and let me know if there is any other better solutions are available from Texas Instrument.

Hello,

For a lot of the lower applications (<2A) you should be able to use the TPSM33625.

For applications 4A+ you can use the TPSM63604/6.

Looking at all your IBB applications, the (-15V/3A) can using the TPSM63606.

For the other IBB applications that have less than 2A, you can convert the TPSM33625.

Please make sure for the IBB conversion, please using the following app note: https://www.ti.com/lit/an/snva856b/snva856b.pdf

Dear Jimmy,

Thanks for your response.

As we are using this DC-DC supply for Precision Signal Conditioning processing circuit. Could we use LDO so that we will not any switching noise on PCB which will merged with precise low voltage signal.

Hello,

Please contact the LDO team to ask for a recommended device if this is what you are looking for.

However I would suggest having these SMPS as a pre-regulator to the LDO which will then create relatively noiseless voltage rail that will power your downstream circuits that may be sensitive to noise.

Regards,

Jimmy
