OMAP-L137 power management chip selection

HarriSiirtola

I've been planning to use a TPS650532 for generating power supplies for my custom board. I want to feed all peripherals separately to minimize interferences. The system has USB, Bluetooth, 802.15.4 radio module and an external A/D converter chip.The TPS650532 provides two DC/DC converters and three LDO regulators, so it could meet my needs nicely (the fifth output would be for the OMAP itself).

Are there any better suggestions for powering a system like this, or other matters to be taken into consideration?

Thanks,

Harri,

This power management forum should be good.

I'm not a power-management specialist, but here are some useful pages in case you have not seen them:

Mariana,

Thank you for sharing this info.

This forum is specific for TPS659xx and we tend to keep it exclusively for that. If we have a lot of questions on OMAPL then I would say it may be better to have a separate power forum to avoid confusion.

Regards,
Gandhar.

Yeah, this post was already moved here before Mariana replied. I take it I still should ask this on the general board? If this one is strictly for that particular IC type, I suggest you rephrase the name of this forum to indicate TPS659xx rather than just "Power Management ICs for OMAP" which seems to mislead people, even TI employees ;)

Should we move this back to general board and continue there?

And to Mariana's reply, thanks! I had already studied those documents and just want to make sure if I understood them correctly. The main uncertainty is if I need more outputs than five.
