Hi Team
I have modified the existing Pspice simulation available on the UCC28951 landing page to make it a 6.6kW PSFB with input of 400V and output of 60V by modifying feedback resistors. No change was made in…
Part Number: UCC28951 Hi , we are currently bringing up a 400W PSFB, Vin=150V-800V, Vout=24V using the UCC28951 PSFB controller.
Currently we have tested at light load and input voltages not greater than 250V. Due to current configuration of the IC…
Part Number: UCC28951 Tool/software: Hi,
I'm currently in the process of designing an isolated DC-DC converter with the following specifications:
Input Voltage: 22-36V
Output Voltage: 20-200V
Output Power: 600W
Isolated
Power over full range…
Part Number: UCC28951 Tool/software: Hi,
Is it possible to bypass burst mode at low load on the UCC28951 ?
The ~10kHz vibrations are less desirable for my application than the losses during the initial battery charge times.
Thanks

Hi Mike,
Hope you are well.
I have a question about the primary clamping diode of PSFB, namely Db and Dc in the slua560 design.
As per your previous answer, the link is shown below. I am confused after…
Part Number: UCC28951-Q1 Tool/software: When comparing the calculation used to determine Lmag and Lout, there is a factor of two (2) difference in the following documents:
Lmag: SLUSDB2B (Equation 28) vs SLUA560D (Equation 8)
Lout: SLUSDB2B (Equation…
