I can't find a way for WebBench to allow for +/- output voltage…
Part Number: UCC28950-Q1 Other Parts Discussed in Thread: UCC28950
We are mass-producing an automotive LDC (Low Voltage DC-DC Converter) using the UCC28950 . However, one of the units is repeatedly malfunctioning . Upon investigation, we found an issue…
Part Number: UCC28950 Hi Experts,
Regarding the UCC28950 with say 750W and Vout = 36V or above. In this case, the ringing of Leakage L with the synchronous FET capacitance will potentially result in overvvoltage of the Synchronous FET.
As such an…
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…
