1. Q1, Q2 form HV startup for VDD, but zener D5 to Q2's gate, can not be breakup to generate a voltage of 25V. so what is…
Part Number: UCC28C56H-Q1 Hello TI.
When unloaded, we have around 95V and when fully loaded we have 62V. Is it possible to improve this somehow? Maybe Rfbu is too high? How can this be troubleshooted?
Attached transformer datasheet, do you think it could…

このボードに搭載されているPWMコントローラICはUCC28C56H-Q1ですが、このICをUCC28C53-Q1に変更すると正常に動作しますか? ICを交換したところ…
Part Number: UCC28C53-Q1 Other Parts Discussed in Thread: UCC28C56H Tool/software: Dear Team ,
in the EVB of the UCC28C56H Q1, we can see the Short circuit to Ground waveforms. I have some qtns on that pls reply :
1. Does the UCC28Cxx family supports…
Hi Seungypo,
Thank you for reaching out.
I think the following references should help in the design of clamp circuit and converting from cascode configuration to 1700V SiC FET option.

Hi Mike,
I'm looking for Flyback QR+SR for high Efficiency and spec is Low input 28V DC and another design 115VAC to 5V, 3A output.
QR Flyback selected UCC28C56H Q1 and SR planning to use UCC24612. it would be great if you have both combined PSPICE…
Hi Toktam,
Steve is out a couple of days due to thanks giving.
Sorry that you were not able to have webench model. But we do have PSPICE model for UCC28C56 in the product folder ready to download for the single switch flyback option.

Hi Bright,
The best way to isolate power path from the control ground would be to have a star connection at the bulk capacitor. So the power return path from the MOSFET source through the sense resistor will terminate in a short path to bulk capacitor…
Hi Valentinas,
The IC itself is a general purpose PWM controller that can support multiple topologies and power levels. The components around the IC would have to change to support 30W from 40V - 100V. Then, after the design can support 30W from 40V …
