No modifications have been made to the hardware feedback and control circuits. The software current loop is implemented following the attached diagram. The hardware and software configurations of the PH1 and PH2 power paths are identical except for acceptable minor deviations. PH1 operates normally, while the PH2 path loses gate drive signals for half an AC cycle during operation. Looking forward to your reply.https://e2echina.ti.com/support/microcontrollers/other/f/other-microcontrollers-forum/1093291/tidm-02013/3935614Tue, 08 Sep 2026 05:09:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:d67380b7-db8f-4e43-b5a7-a26485333762hisen heDear Expert, Our hardware circuit is based on TI reference design TIDM-02013.

Afterwards, the Lab 3 current‑loop test was carried out. When only the PH1 branch was enabled with a 200 Ω load connected, the output voltage rose gradually as the current‑loop reference was increased step‑by‑step. Finally, with a current reference of 0.17 and 220 V AC input, the output voltage reached 400 V, and the power factor was higher than 0.99. However, under identical test conditions when only the PH2 branch was enabled, gate drive signals were missing during the negative half‑cycle. Increasing the current‑loop reference failed to restore the missing drive pulses. In Figure 1, the blue trace shows the gate‑drive waveform of PH2. In Figure 2, the yellow trace denotes the input voltage and the blue trace denotes the input current. Due to this fault in the PH2 branch, the interleaved totem‑pole PFC cannot work properly. What could be the root cause? Is it an issue with the Hall‑effect current sensor, or a firmware/code‑related problem? This issue has troubled me for a long time. I look forward to your prompt reply.

I followed the instructions you provided, but it appears that the current webpage structure may have changed, and I was unable to find the entry points you described. Specifically: 1. When opening `ticsc.service-now.com/csm`, the page remains stuck in a loading/redirecting state and does not display the "Request a New Support" or "Submit an Application for the Family" buttons you mentioned. 2. I also tried navigating through the "Support & Quality" section on TI.com.cn, but still could not find a submission path that matches your description. Could you please provide an updated guide or a direct link? For example, is there a way to submit a quality-related case directly through my TI account page? Or is there an email address I can use to send the X-ray inspection results and a description of the issue to the relevant team? I look forward to your further guidance.

As shown in the attached X-ray images, there appear to be internal lead-frame protrusions on the side of the body of the device. These protrusions extend outward from the main lead-frame structure and are visible on both the top and side views under inspection. We have highlighted the areas of concern in the images for reference. Could you please help confirm: Are these protrusions a normal characteristic of the lead-frame design for this device? Could they potentially impact the mechanical or electrical reliability of the part, such as the risk of short circuits or die attach integrity? Is there any known process variation that could cause such features, and do they fall within TI's standard acceptance criteria? Any clarification or guidance would be greatly appreciated.
