Part Number: UCC28951-Q1 Other Parts Discussed in Thread: UCC28951 , PMP8740 Tool/software: I've following questions related to HV-LV converter: 1. In TIDA-020031, how it is ensured that LV battery is charged in cc cv mode?
2. In EV architecture the…
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
Hello,
I looked at your simulation file and your feedback capacitors seem to small. You might want to check the compensation.
I also see the compensation capacitors (C3, C4) have an initial voltage across them. This may be causing your design to over…
Part Number: UCC28951 Tool/software: Does the UCC28951 clamp or pull down the CS pin once the peak current is detected? I have a generic spice simulation (open loop, without the controller) showing the CS signal does not go to zero after the peak; there…
Part Number: UCC28951-Q1 Tool/software: Hello mike.
I'm trying to adjust compensation and TMin values and have bought the board to this stage. Below I'm attaching waveforms and videos.
This is higher voltage lower loads currents.

Part Number: UCC28951-Q1 Other Parts Discussed in Thread: UCC28951 Tool/software: Dear Sir,
I am currently designing a DC-DC converter using the PSFB configuration, with an input voltage range of 16.8V to 90V and an output of 48V at 30A. I require both…
Part Number: UCC28951 Tool/software: Dear Sir,
We are using UCC28951 for designing PSFB Board for 4kW Charger. Can you give the procedure to do Fixed delay approach in UCC28951 for getting uniform DT. The dead time(DT) is Non-Uniform and there is a difference…
Part Number: UCC28951-Q1 Other Parts Discussed in Thread: UCC28951 , Tool/software: Dear Sir,
We are unable to check current sense current using KEYSIGHT InfiniVision MSOX3024T oscilloscope with High Voltage probe, Can you advise how to do that for UCC28951…
