Part Number: UCC28730-Q1 Other Parts Discussed in Thread: UCC28730 Tool/software: Hi Team,
We are facing an odd problem. We found the frequency of the UCC28730 output is not as expected. According to the datasheet, the max switching frequency should…
Part Number: UCC28730-Q1 Other Parts Discussed in Thread: UCC28730 Hello,
We have a concern about creepage at UCC28730-Q1 device.
We have detected that in our design, we will have up to 510Vrms between HV pin and DRV pin.
We need to ensure that…
Part Number: UCC28730-Q1 Tool/software: We are designing our Flyback circuit with 400Vin and 18Vout, 13W using this controller.
I have used datasheet to calculate Rcs,
for an efficiency of 85% and ηxfmr of 91%, Nps = 6; Rcs can be calculated from…

Hi,
One of the reference designs for UCC28730 shows HV pin pull resistance of 900k for 60V-1000V Vin. (Refer image)
According to datasheet, the start-up current…
Part Number: UCC28730-Q1 Other Parts Discussed in Thread: UCC28730 Tool/software: Hi Team,
I would like to know is there any possibility if added circuit to can control the line voltage precisely about 50 +/- 3V using UCC28730-Q1
Below is the…
Part Number: UCC28730-Q1
Tool/software:
Hi,
According to the datasheet, the minimum ON time of the MOSFET should be greater than t-csleb (leading edge blanking time).
For my application, the design calculator suggests ~700uH of primary inductance…
Part Number: UCC28730-Q1 Tool/software: I have designed a 23 W Flyback-Converter with 1Outputs with a Inputvoltage of 250-800V and an Outputvoltage of 11V/2.1A. I am now trying to put the PCB in operation, but I am facing unstable switching behaviours…
