TMS320F28335: How slope compensation is implemented

Part Number: TMS320F28335
Other Parts Discussed in Thread: C2000WARE, TIDM-02000

At present, there are only F28335 chips in hand, and no other chips. Seeing the previous post, it seems that there is a way to compensate for the slope. Is there a example code?

Please see TIDM-02000 code in C2000Ware. It uses slope compensation for a peak current mode controlled PSFB DC/DC converter. If you download C2000Ware then you will find the design in this folder

F28335 Is it possible to achieve slope compensation by modifying this 28004 example?

We have made significant enhancements in F280049 with regards to PCMC with slope compensation. F28335 does not have those enhanced features.

So, F28335 implementation of PCMC/Slope compensation is different from F280049 based approach. The later is simpler because of MCU internal enhancement.
