Part Number: UCC28712 Other Parts Discussed in Thread: UCC28710 , , UCC28711 , UCC28780 Hello
We have a module use generally use UCC28710 dbr and it works fine.
Due to shortage , we bought some UCC28712 thinking it should make no difference because…
Part Number: UCC28712 Hi,
i am working on aux power supply using a ucc28712 and multioutput custom made sumps transformer for the design ,use the ti design calculator for resister values (Rs1,Rs2,Rcs,Rlc) but still couldn't able to get outputs
i have…
Part Number: UCC28712 Other Parts Discussed in Thread: PMP22557 , UCC28910 ,
I've attempted a HV buck converter design based on the PMP22557. The desired output is between 12V and 36V (adjustable) with ideally 5A max output. Only one MOSFET is populated…

HI Team,
I am working on UCC28712 Flyback configuration, thing is i am facing issue with start-up means. I are observing pin 7 HV getting High voltage from rectifier which is 210VB, but we are not seeing capacitor charging…
Part Number: UCC28712 Other Parts Discussed in Thread: UCC28C42 Hi Team,
Do you have reference schematic design using UCC28712D whose
Input is 8V DC - 45V DC
Output 12V DC / 1.7A DC
I cant able to get the information from Webench . Kindly share…

Hi Experts,
Please help clarify/confirm if UCC28712 can output 5V1A and 20V3.25A.
Also, can it output 65W? Is a demo/simulation available to make sure UCC28712 work in 65W?
Thank you and best regards,
Gerald
Part Number: UCC28712 Hello -
We are attempting to startup our flyback power supply but are running into issues. We are using the UCC28712 controller.
We see Vdd charge to ~ 21V and then the gate pulses 1 time. The pulse width of the gate signal is…
Part Number: UCC28712 Hello -
We are experimenting with the UCC28712 in a 24V power supply design. We are using a SiC MOSFET as the primary switch in the flyback circuit. During startup, we observed the following waveform where the blue trace is the…
Part Number: UCC28712 Hello - we are attempting to use the UCC28712 as the controller for a 24V, 1A power supply. The nominal input voltage is 800V.
The device starts up at an input voltage of ~ 300V.
When the load is ~ 100 Ohms, we can see the output…
