Dear TI Team,
I have selected the UCC28C56H controller for my flyback application and have been performing the design calculations using the UCC28C56H-Q1 datasheet…
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 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 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 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…
Hi Hong,
Hong Huang said: It looks ok to me to use UCC27714 for synchronous rectifier boost. Q2 is for boost control and Q1 is for SR.
OK, We are considering using the UCC27714.
However, is the combination of UCC28C56H + UCC27714 the most optimal…
Hi,
UCC28C58-Q1 is created to work with SiC MOSFETs. Please check your MOSFETs driving voltage rating if ok to use UCC28C58-Q1, or other members in this family, UCC28C56H, L, UCC28C57H, L, or UCC28C59. Note its on chip driver is with peak current up…
