Part Number: UCC28750 Tool/software: Hi team,
Does UCC28750 can support QR flyback? Customer is requesting for a QR controller, and which device is the most competitive to promote?
Thanks!

Part Number: UCC28750 Tool/software: Hi,
Im using UCC287506 Power management IC. Im planning to have an Overvoltage protection above 400 Volts. I have connected the circuit as below. However at The fault pin of the IC im reading only 2.5 volts across…
Part Number: UCC28750 Tool/software: Hello team,
We are planning to use ucc28750 for multiple output power supply design, so can we use simple resistive voltage divider at FB pin instead of using opto-coupler? We can compromise with isolation. Please…
Part Number: UCC28750 Tool/software: Hello, I have designed a power supply using UCC287506 to be operated on 100kHz, 12 watt output power. I am facing an issue during startup at full load. My observation is that during startup the controller is switching…
Hi Simon,
Try reducing the Current sense value well below the calculated resistor value say 40 to 50%. You might be able to achieve the over power application.

Part Number: UCC28750 I am looking for a component that, together with an electronic design, converts 540V (DC) input into 28V (DC) output with a current output range of 1A to 3 A.
After doing a search, I found the UCC28750 chip, but there is no PSPICe…
