Part Number: UCD3138FW-PSFB Hello:
The LLC expert refers me to ask the following question to PSFB experts. So here you go.
Fortunately for us, the modified LLC breadboard by putting in our values just to ensure we get a better understanding of the circuit…
Hello Chieh-Yu,
I shared the link above but I will share the link again: https://www.ti.com/tool/UCD3138FW-PSFB
I also sent you the direct .cproject file that comes with the UCD3138FW-PSFB.

Hello
I am trying to evaluate the UCD3138PSFBEVM-027.
I connected the USB-TO-GPIO2 to the UCD3138CC64EVM-30 and was able to scan the…

Hello
I imitated the PSFB development board of UCD3138 to make a power supply prototype,
and encountered a problem when doing load jumps.
When the load jump amplitude is small, such…
Part Number: UCD3138FW-PSFB Other Parts Discussed in Thread: UCD3138 Hello,
I imitated the PSFB development board of UCD3138 and made a power supply,
and found that when the loop bandwidth is 6kHz, Vo will oscillate obviously when the load jumps from 0A…
Part Number: UCD3138FW-PSFB Hello
I recently tested UCD3138-PSFB EVM and found two problems:
1. When the development board is unloaded and slightly loaded, the phase shift angle of the primary switch tube is very different. When there is no load, the…
Hello Koumei,
Do you have a screenshot of the UCD3xxx Device GUI and the error message you receive?
If you are currently running the UCD3138 in flash mode, then you can click on DEVICE_ID to ensure communication between the UCD3xxx GUI and the UCD3138…
Part Number: UCD3138FW-PSFB Other Parts Discussed in Thread: UCD3138 Hello
I imitated the PSFB development board of UCD3138 and made a power supply
During the test, it was found that the output voltage was the target value when the prototype had a load…
Part Number: UCD3138FW-PSFB Hello, I made a power supply modeled on the PSFB development board.
When debugging the load jump from 6A to 10A, the synchronous rectifier is damaged, the waveform is as follows:
The green curve is the output current, and…
Hello Sandip,
Other considerations could be power density, desired complexity, etc. At 1kW, both LLC and PSFB are common. UCD has resources for both LLC and PSFB topologies. I do not believe we have 800V input designs but we do have 1kW designs for both…
