Hi, Sanghyun,
Do you have to keep the same transformer and snubber cap or you are open to change the power stage?
I am not sure where you read UCC28950 is not efficient when input voltage is low. 48V input is not low. Can you point me the source of your…
Part Number: UCC2897A Other Parts Discussed in Thread: PMP9656 Hi TI partner,
Currently, I'm design ACF topology that using UCC2897A for Vin:43V~60V to Vout:12V/21A application, as below is my design questions list, need your help to clarify them.…
Hello Elvis,
If TI replaces a reference design then there was an issue and it was in everyone's best interest to stop promoting the design. I see the NA5738-DL data sheet states only 52-60V input, while the replacement transformer ( RA6992-BL ) states…
Part Number: UCC27511 Other Parts Discussed in Thread: CSD18532Q5B Hi team,
Customer is using our reference design PMP9656 to in their project. This design use 2 pcs UCC27511 drive 4 pcs MOSFET at the secondary side. And the MOSFET use CSD18532Q5B, it…
Hi
600 W is high for this topology but 300 W is certainly achievable with good results. One example is PMP9656 , which is an active clamp forward using UCC2897A as the controller. The PMP9656 ref design input voltage range is slightly higher (47 V<VIN<60…
Part Number: UCC2897A Other Parts Discussed in Thread: PMP9656 , TL431 Tool/software: WEBENCH® Design Tools I am trying to design an isolated DC-DC converter using UCC2897A
I tried simulating by considering the reference design of TI PMP9656. I have made…
Part Number: UCC2897A Other Parts Discussed in Thread: PMP9656 , Tool/software: WEBENCH® Design Tools I wanted to simulate a 36-75V input ,12V/20A output design (PMP9656). Wanted to know whether it is available. when i check in WEBENCH , it is showing as…
Hi Sir, Thank you for your guidance. As you suggested me to use Active clamp forward converter topology and suggested me to use UCC2897A Controller and PMP9656 for Reference Design. But This design is for 12 V Output. So will it wok for My Vo= 24 V. ??…
Hi Nayana,
Generally speaking, active clamp forward is a good choice for low voltage/high current type outputs. What is your input voltage range? This can influence your topology choice as well.
You also might be interested in PMP9656 which is a 12V…
