Hello,
I have designed a custom board based on the TIDA-00705 reference design. I have used the same parts you provided in the schematic. I'm using TIDA-00705 Firmware that you provided for this board.
After programming and calibrating the board, it works as a boost converter (charges the battery), but does not work as a back converter when turn off the 12 V terminal. The oscilloscope shows that at the moment of turn off the 12 V there is no PWM signal on the DPWM pins.
Could you please advice me something where to look for the mistake and (or) what sequence of actions to use for searching?
Thanks,
Egor
