Hello,
These device parameters are documented in the data sheet. I am not sure what you mean by variations standards can you clarify?
In regards to aging of the devices the following link has information that should be helpful in answering these questions…
Part Number: UCC28950 Hi team,
My customer is developing a PSFB power supply, and they intend not to use SR to save more cost. And the product does not have high efficiency request.
UCC28950 seems a good option, and I would like to confirm whether this…
Part Number: UCC28950 Other Parts Discussed in Thread: UCC28951 , UCC2895 Dear Team,
My customer would like to use a full bridge phase shift controller like the UCC28950 however he would like to operate it at low switching freq (Fsw).
On the UCC28950 recommended…
Part Number: UCC28950 Other Parts Discussed in Thread: PMP8606 Hi Ti team
I am using UCC28950 Phase shifted full bridge for EV charger development
Power=3500W,Vinput =380V DC to 425V DC output is 340V to 450V DC
I am using UCC28950 IC in Primary side…
Part Number: UCC28950 I have a question about the startup waveform of the power supply using UCC28950, I would appreciate your answer.
Please refer to the waveform.
When the purple waveform goes to Low level, the startup has begun.
Next, observe the yellow…
Part Number: UCC28950 Other Parts Discussed in Thread: UC3526 , UCC29002 Currently, I have designed a DC-DC isolated converter using UC3526 and push-pull topology, which provides 36-60VDC input and 96VDC output. These designs have turned into 900W modules…
Part Number: UCC28950 Hi,
Sorry for asking so many questions.
I have some additional questions about soft-start.
I tried the operation test with UCC28950 alone by not inputting feedback signal to UCC28950.
Please refer to the attached file.
When VSS voltage…
Part Number: UCC28950 Thank you for your response.
I have an additional question.
I would like to ask how the converter can operate with soft-start.
Please refer to waveforms.
When the VSS voltage reaches 0.55V, several pulses of the OUTA ,B signal are…
