Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Part Number: LM5025B Dear！
I used LM5025B to design a forward circuit. The input voltage is 16-40V, and the output is 5V@16A. When the input is 16V, the output can only be loaded with 7A load. If it is larger, it will appear the phenomenon similar to…
Part Number: LM5025B Hi support team
LM5025 can support both applications to use P channel and N channel as active clamp switch.
In the datasheet and LM5025EVM, The application using P channel FET as active clamp switch only has been shown.
Do you have any…

Part Number: UCC2893 Other Parts Discussed in Thread: UCC2891 , UCC2892 , UCC2894 , UCC2897A , LM5025C , LM5025B , LM5025A , LM5026 Hi,
Any alternative suggestion to UCC2893 controller? Thanks

Hi,
Yes, increase UVLO off can help reduce the switch node voltage. This device maximum duty cycle increases when input voltage reduces, and this device maximum duty cycle can go as high as close to 90%. From the volt-seconds balance, Vds = Vin/(1-D),…
Part Number: LM5025AEVAL Other Parts Discussed in Thread: LM5025B , , LM5025A , LM5025 Hi, I´m evaluating the LM5025B Eval Board (3.3V@30Aout) due to the need of sync in a wide band of frequency. The result I´m getting is that for big frequency changes through…
Hello Anindya,
Most application of the active clamp use a low side p channel reset FET probably because it is so much easier to drive this part.
However there are advantages in using an n channel FET in certain applications. Application note SLUA322 describes…
