  • UCD3138FW-PSFB: UCD3138-PSFB EVM no-load and dead-load problems

    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…

  • UCD3138FW-PSFB: The output voltage of PSFB based on UCD3138 is too high when there is no load

    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…

  • UCD3138FW-PSFB: PSFB power supply based on UCD3138 has output voltage drift when no load and synchronous rectifier damage when load jumps

    TI Thinks Resolved
    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…
