Tool/software:
Hello mike ,
1. The schematic is same, no changes done. Im using clamp diodes with shim inductor. This is message is in relation to the previous post you…
Part Number: UCC28951 Tool/software: Hello,
I’m still having difficulty setting the timing that I require using the UCC28951. The equations do not seem to give me the correct values. Instead, I must experiment with values in the lab to get reasonable…
Part Number: UCC28951 Other Parts Discussed in Thread: UC2875 ,
Tool/software:
hi,
we are replacing UC2875 with UCC28951 as unique option.
For our product, we absolutely need a controller that can operate at a switching frequency of 20 kHz, while…

Tool/software:
Testing using SiC MOSFETs
Scenario: Vin:810VDC, load : 43Adc
Below are gate drain source of primary MOSFETs. Resonant inductor is not being used. Transformer leakage…
Part Number: UCC28951 Tool/software: Hi,
I am designing a 5kW phase-shifted full bridge regulator using the UCC28951. I am having trouble maintaining soft switching on my A/B transistors, which is preventing me from reaching high loads. I can achieve…
Part Number: UCC28951 Tool/software: Hello, I would like to run a simulation including the UCC28951 controller in a SPICE software that is not PSpice, would TI be able to provide an unencrypted transient model for the controller? Thank you, Nicolas
Part Number: UCC28951 Tool/software: Hello,
In the datasheet for UCC28951, the equation (2) to calculate the soft-start capacitor during follower mode seems wrong.
The numerator should not have 25uA.
Regards
Part Number: UCC28951 Tool/software: We have designed a 1KW, ±80V output switching power supply for the amplifier, and we would like to consult on two questions:
How can the dual-voltage feedback ensure that the absolute values of the two voltages…
Part Number: UCC28951 Tool/software: Hi Team,
I have a question on the allowable negative voltage rating of UCC28951, I guess "-0.4V" here refers to the continuous voltage rating applied on the IC pin.
How about the transient voltage rating with short…
