Part Number: UCC28950 Tool/software: Hi I am trying to design a DC-DC converter using WebBench with the following specifications
Input V 20-30 VDC
Output V +/- 85VDC
Output I 10A
I can't find a way for WebBench to allow for +/- output voltage…
Part Number: UCC28950 Tool/software: Hi,
I am currently implementing and testing a PSFB converter using the UCC28950 chip.
I have a question about the Tmin setting. The datasheet states that Tmin should be set to the minimum duty cycle that allows…
Part Number: UCC28950 Tool/software: Helo all. Some weeks I try to create power from lead acid 24V to 80 V 1500w . Ihave created prototype, but still problem with snubber diodes and resisors in output synced rectifier. I use two types of wiring with resistor…
Part Number: UCC28950 Tool/software: Hello guys,
One of my customers is evaluating UCC28950 for their next products.
At this moment, they have a question about this device operation. But they don't want to disclose their question on this E2E.
So…
Part Number: UCC28950 Other Parts Discussed in Thread: TINA-TI Tool/software: Hi,
One of our customers is currently developing a phase-shifted full-bridge power supply using the UCC28950 and has requested that we provide phase margin and gain margin…
Part Number: UCC28950 Tool/software: Hi,
We have observed unexpected waveforms during the startup of a switching power supply using the UCC28950. The details of the issue are summarized in the attached Excel sheet for your review. UCC28950_20250729…
