Other Parts Discussed in Thread: PMP41009 , UCC28740-Q1 , UCC28740 , UCC28742 Hi，May I ask if I can replace the UCC28740-Q1 chip in the PMP41009 design circuit with a chip from the UCCx8C5x series? If not, what is the reason? Can chips from the UCCx8C5x series…
Hi
Yes, two secondary winding makes sense for dual rail output. However, needs to be very careful about circulating current and transients on secondary side. Could you please share complete WEBENCH design.
Part Number: AFE5932 I have ordered 2 pieces of the AFE5932 chip and intended to review the technical documentation. However, I found that the official documentation is missing key content, including block diagrams, typical application circuits, package…
Part Number: LMH13000RQEEVM Hello:
LMH13000RQE Evaluation test circuit :
Spec calculation formula
Estimate based on formula
Iout Test Results: The test results of the development board are different from the calculation formula. Is there a problem with the…
Thank you for your reply.
I am not the original designer of this circuit, therefore I am not sure. I worked with a freelance PCB developer, which I forwarded your questino.
Do you think C21 is causing the problem?

Hello, I am debugging a self-designed flyback switching power supply with an input of 90-900VAC and an output of 24VDC. I use the UCC28740 chip and adopt the relevant power supply…
Yes, I previously designed a circuit based on that idea, but when I made the board, I found it was wrong. The board doesn't work properly.In fact, neither of the two JFETs in JFET40 is working.
Hi，
We do not have a reference design for STM32.
You can refer to the "7.4.10 Frame Sync Data Port" design on page 65 of the datasheet, https://www.ti.com/lit/ds/symlink/ads127l18.pdf
and you can also refer to EVM board circuit， www.ti.com.cn…
