Hi,

Do you have any examples on how I would be able to implement soft start on a buck converter in code? The goal is to control the increase of the output voltage.

    Mike,

    You can find soft start in main.c as shown below in TIDM-DC-DC-BUCK reference design. You can find the definition in hal.h by cntrl+click the function:

    Slew step can be adjusted as shown in user_setting.h. Slew rate can be calculated as using this step and ISR frequency.

    Regards,

    Sumit
