Hey Ben,
Since that is beyond .bt spec limit, they have to choose between a few options.
1. They could use 2x TPS2372 with a single RJ45 port in Beyond BT application
2. They could do a dual PD and dual DCDC that combine at the output to deliver greater…
Hello Vijay,
From your requirements you want dual output (12V and 24V). A buck regulator will only provide a single output. Also, Webench is only good for single output designs. So, based on the power requirements one possibility is the forward converter…
Part Number: PMP9656 Other Parts Discussed in Thread: PMP8861 Hi team,
My customer followed the PMP9656 and successfully built a design for 48V to 12/20A applications. Now they have a new project, hoping to extend the input voltage range to 24V-48V, but…
Hello Yue Tang,
The UCC2897A is a similar part to the LM5025A
PMP8861 reference design is an 18-72VDC Input, 12V/120W Active Clamp Forward Reference Design.

The image you have shared are for 12W supply, we are designing for 120W supply with below specifications:
input 18V to 80VDC & output 24V, 5A
we wish to have the 120W transformer information as shared by you for 12W supply. we are unable to get this…
Hi Jim,
Thanks for contacting us regarding your WEBENCH design. Your output is fairly high current and probably beyond what WEBENCH would consider "standard." The WEBENCH designer algorithm designs the transformer taking into consideration several factors…

At this voltage and power level we recommend one of our active clamp forward controllers like UCC2897A. http://www.ti.com/tool/PMP8861 is an example design that is close to your design target. Please note that at 1.2V output is below the range of…
Hello Sreenivasa,
If this design was made for a 12V 2A (24W) output then you will not be able to get a 4A (48W) output without redesigning the circuit.
You can use the Excel calculator for the UCC2897A to help with the component selection and you can…

We do not have a reference design with UCC28740 with such a low input voltage nor do we recommend it be used with such a low voltage. UCC28740 is designed for offline AC/DC supplies where the input voltage is typically 85-265 VAC. It includes features…
