Hello Le Duc,
Yes, this part is more than capable to support your application. You can look at this reference design for input filtering but you will likely have to adjust it based on the standards you are trying to meet. We tested the reference design…
Hello,
Please look at PMP15004, it meets CISPR25 Class 3. I have also used this board and met CISPR 25 Class 5 level in an enclosure.

Hello,
CISPR 25 level 5 is difficult to reach. Look at PMP15004. This design meets CISPR 25 level 3. I placed an enclosure around it, bypassed the input and output and reached CISPR 25 Class 5 with our internal testing. Your input voltage must be higher…
Hello,
I calculate:
Fsw = 143 KHz
maximum di/dt = 2.2A (at 32V input, 10.2V output) This means the inductor needs to be able to handle over 2.3A peak.
Iave = 1.2A
It cannot regulate current when Vout is greater than Vin, your Vout maximum is…
Hello,
This is part of the design process. When you calculate a design you have Vin, Vled, Iled and a switching frequency at an operating point. The MOSFET is internal. The inductor needs to be able to operate at the switching frequency chosen and current…
Hello Hazel,
Each of these parts have reference designs that have EMI or EMC testing done with those reference designs. They are easily found on the landing page, see below:
Specifically, the TPS92515 also has multiple reference designs that include…
Part Number: LM3409HV-Q1 Other Parts Discussed in Thread: LM3409 , PMP15004 , TPS92515 Hello Group,
I have been struggling with this for a bit and wanted to get this question out here. I see a lot of information in these forums, so I am eager to see…
Hello Philipp,
Again, EMI is a system issue, this will be nearly impossible to solve via e2e. PMP15004 is a TI design That I did that passes Class 3 automotive limits in house, stand alone, which is much more strict than FCC Class B.
If your LED…
Hello Irwin,
thanks for your answer.
So did I understand correctly that with a design like PMP15004 or any other design with very clean input and output, a relatively large load or a load placed far away will not significantly degrade EMI performance…
