TMS320F28027: Push-pull switching power scheme

Hi Cherry,

Cherry Zhou said:

1. The customer would like to know if TI has the similar or same push-pull switching power supply scheme.

Does this control take SFRA and DCL, or other control method to control the duty cycle of the PWM?

We have an old design which is https://www.ti.com/tool/TIDM-BIDIR-400-12. The boost mode utilizes pull pull topology.

2. Also, is there any other way or software to burn chips in bulk?  CSS for the is too large. 

Could you explain your question again? I don't quite get it.

Hi Chen,

I just hear back from the end customer:

The customer would like to know is there any way to implement burning multiple chips at a time.

Also, may i know where can i get the code in this scheme? 

Thanks and regards,

Cherry

I assume you are referring to use single CCS to load the code for multiple MCU at a time?

The code is in the routine below. Customer needs to download the controlSUITE from ti website. 

C:\ti\controlSUITE\development_kits\BI_DIRECTIONAL_DC_DC_400_12

Note this solution is based on f2803x and we will consider to move it to newer devices next.
