Part Number: TMS320F28027
Other Parts Discussed in Thread: POWERSUITE, C2000WARE, LM3410

I am looking for a sample code for a boost controller using the F28027. Should I look at a different microcontroller?

Hi Carl,

The F2802x is likely a good choice.

Is the application a PFC application?
How many boost stages are you looking to control?

Generically, I might recommend the following application kit & its software as a starting point. You can find more details on where to find specific content for it within the description on its evaluation kit product page:
http://www.ti.com/tool/TMDSRGBLEDKIT

Depending on some of the answers to the questions above, there may be options within the newer & potentially better solutions within C2000Ware/PowerSUITE.

Thank you,
Brett

We have one boost stage and using it to dive high power LEDs. Also, the F28027 is being used to controller various other features we are implementing.

Also, this is not PFC.

Hi Carl,

Then yes, from a C2000 standpoint, I'd consider what I mentioned as a good starting point for you.

I'm from the C2000 group, and so I'd be fine with you choosing to go with a C2000 device. :)

However, another approach may be to use a TI analog-controlled boost controller along with a cheaper/simpler TI MCU.
(something like a LM3410 + MSP430FR*)

In my mind it would really depend on what those other features you'll need the MCU to do (up to you to determine applicability), potentially operating temperature range (C2000's range is larger than MSP), and quiescent current (MSP consumes less power than the C2000).

Note that I'm not an expert on the best analog power products, so if you go that direction, it'd probably be worth asking that portion of the forum for advice.

Hopefully this helps!

Thank you,
Brett
