Part Number: UCC28750 Tool/software: Hello,
I am trying to make 24V to 5V converter with the UCC287506DBVR. You can see the converter on the schematic below.
When I power it up I don't have any oscillation on the DRV pin while I should have 100kHz…

Hello,
I am creating a design for universal input from 85-265VAC , 50/60Hz frequency with Two Dual Isolated output 12V,0.5A and 5V,0.2A. I have used…
Part Number: UCC28750 Tool/software: Hi,
I found an issue where, under full-load conditions, the system enters protection mode during a circuit short. However, after releasing the short, the system fails to resume normal output. Strangely, it recovers…
Part Number: UCC28750 Tool/software: Hi All,
I'm looking for a flyback controller for ACDC that can be used with AC24V.
UCC28750 seems good, but are there any other products you would recommend?
Is there a list of ACDC flyback controller products…
Part Number: UCC28750 Tool/software: I am attempting to use the UCC287502DBVR in order to generate 12V max 2A. When I plug in my PCB, I get 0V out at the output. Voltage (carefully) measured after the bridge rectifier is ~172VDC, and the VDD pin on the…
Part Number: UCC28750 Tool/software: Hello,
When I plug in my board to AC power, I get regular but slow flickers from my output power LEDs, but then when I unplug the device, it clicks and then VDD is shorted to ground next time I plug the device in…
Part Number: UCC28750 Tool/software: Hello everyone. Using the UCC287502dbvr integration, I am making a flyback with 130v input 12v 6a output 72W output. But I get the output as 0. When I observe the supply of the input, I see that it is not fed. Obviously…
Part Number: UCC28750 Tool/software: I am designing a 150W Flyback converter with 85VAC-265VAV input and 24VDC-6A output using IC UCC287502.
When I supply 15V DC voltage to the VDD pin of the IC, the converter works stably, 15V I get from an external…

Part Number: UCC28750 Tool/software: Hi TI Team,
Good Day!
I would like to know if it’s possible to achieve an isolated DC-DC conversion from 400V to 12V using the UCC28750 without using a transformer.
If yes, could you please share any available…
