TMS320F28335: Phase-shift behaviour for 28335: how does it work in a pwm converter?

Carlos Bianchin

Part Number: TMS320F28335

Hi. I´m using 28335 with phase shift converter in pwm channels, but it is not working. During running it loses phase shift value, even with a command in program forcing a value. Anybody have used it in power converter?

Thanks a lot Gautam. The docs you recomende I had just read all of them. Actually I have programed 28335 and it is running but just when I put my power converter to run phase shift stop working. I checked command and value in the register and they are correct but on the output pin regard to the pwm signal shifting doesn't appear.
