Hello,
I would like to simplify the power supply circuit to generate 1.26v and 3.3 for
DSP. Currently I am using 2 of TPS54310 to generate these voltages. And there
are too many passive components I have to used. I would like to reduce the
component count.
Could you please let me know or recommend me a simple power supply circuit for
TMS320C6412?
Thanks,
-Y

Here is the TI page for dual output LDO switchers:
http://focus.ti.com/paramsearch/docs/parametricsearch.tsp?family=analog&familyIdf0&uiTemplateId=NODE_STRY_PGE_T
For sure you can find one that is small with low component count.

Hi Jeff,
Thanks for the link. I was looking for power supply which can supply more than 3Amps current.
Any hint what is normally used with DM642 TI chipset.

Didn't that page show devices like TPS54386? Vin 4.5V to 28V, dual 3A outputs at 0.8V to 90% Vin, 14-pin SSOP,
internal compensation. I don't know the external component count, but seems like it might be low. There's an EVM
board for it.

Have you looked at the EVM DM642 board schematic? What's used on that board?

Thanks Jeff. Looks like TPS54386 is a prefect fit for our design.
