Part Number: UCC2893 To create an active clamp circuit of a flyback type power supply circuit by using a UCC 2893. I calculate with PSPICE, but the operation waveform is unstable and does not converge. It is considered that the cause is the constant of…
Dear Jaden
Thank you for the advice.
I am cosidering power supply for audio equipmet.
The specifications are as follows.
UCC28780 ：±16V （Feedback is given from -16V to + 16V using a center tap transformer.)
Would you please take a look at the…
Hello Hide,
There is a 3% variation on VREF and a 4% variation on RAMP. You can see this from the data sheet for the LM5025.
I am not sure if the distribution data is available for these parameters.TI has several other active clamp controllers such as…
Part Number: UCC2893 Other Parts Discussed in Thread: UCC28780 Hi,
I'm investigating a main switch failures on a flyback converter with active clamp topology. I'm are seeing an event where the output gate signal of the UCC2893 does a kind of hiccup…
Other Parts Discussed in Thread: UCC24630 , UCC2891 , UCC2893 , UCC2897A Can UCC24630 use active clamp circuit?
For example, UCC24630 + UCC2897A (or UCC2891 ~ UCC2893)
Datasheet written that UCC24630 application is Flyback and Forward.

Best regards…
Part Number: UCC2897A Hello Teams,
I have some questions under URL's Design Calculator.
SLUC662 Calculation tool | TI.com
1. B32 are wrriten "Curent Transfer Turns Ration".
What should I write here ? Is it the current transfer of the chart…
Mahesh, Billy,
Maybe I can add more info here to help.
The datasheet for UC1525B says that it's not recommended for new designs, in big red letters across the top of every page - so really, it's best avoided.
The UC1525B is a very old bipolar…
I'm designing a high-power UCC2893-based supply with a CT for sensing current. In my system, the PWM IC isn't right next to the CT because of large components and the heatsink.
What parts should go near the CT and what parts should go near the…
Part Number: UCC2897A Hi Sir,
In the document "Understanding and Designing an Active Clamp Current Mode Controlled Converter Using the UCC2897A"
Can any one clarify below equation, how to get 12.5db at 8kHz frequency.
I have considered all the…
UCC2893D is used for DC/DC controller, UCC2894D can be used as AC/DC offline controller. Can I use UCC2893D in AC/DC offline application? I have this question because I did use UCC2893D for AC/DC application with PIN16 floating. It is an AHB topology…
