Part Number: LM5122 Other Parts Discussed in Thread: PMP9256 ,
Hello, I found that in PMP9256 can be used 2 types of transformers. Base case (in www.ti.com/.../snvr384a.pdf ) - PA6605-AL. As I understand some components from DNP should be installed…
Part Number: LM5122 Other Parts Discussed in Thread: PMP9256 Hi Team,
The test result using the LM5122 EMC control was failed.
Circuit design reference PMP9256.
What other documents do you need for your reference?
Please provide design suggestions…
Part Number: LM5122 Other Parts Discussed in Thread: PMP9256 Tool/software: please share the schematic and BoM of evaluation board with transformer PA2398NL.
Hello Neo The LM5122 does support a synchronous flyback topology. See the following reference design: www.ti.com/.../PMP9256
Also, with a simple additional Zener diode, the LM5122 will also support latch off. See chapter 7.4.3 in the datasheet: If a…
Hi,
There is no exact match. A similar is like this PMP9256
Your output power is 3 x difference. So you may need three different designs, one for 60W and 90W, one for 120W and 150W, and one for 180W.
Your input voltage range is very wide about 11…
Hi Eric,
A flyback should be able to meet your design requirement. You may be interested in PMP9256 which is a 9V to 60V input, 12V/5A output reference design: http://www.ti.com/tool/PMP9256

Hello Larry, Thanks for reaching out to us via e2e.
There are three reference designs on our website which are utilizing the LM5122 for an isolated or non-isolated flyback design:

Hi Jasbeer,
1. The LED driver should be connected to VDD-RTN side of the PD controller. Otherwise, it could affect detection.
2. PMP7499 was not designed for a 12V input. Rather, I recommend looking at the PMP9256 which has a wider input with the…
Hi Lenna,
What is the isolation requirement of the design?
It should be possible to achieve 92% efficiency with a synchronous rectifying MOSFET on the secondary side but it will depend on component selection. PMP9256 is close to the application…
