Part Number: PMP9175 Dear engineer
Hi, I'm Taku.
I designed the power supply circuit of PoE with reference to the circuit diagram of PMP9175.
#Almost imitated the design of PMP9175
Now i check my prototype,
then a very large ripple voltage is applied…
Hi Emma,
Thanks for reaching out!
PMP9175 ( www.ti.com/.../PMP9175) is a reference design for 5V/2.3A Class-3. PA6340-AL is used as transformer.
Best regards,
Diang
Part Number: PMP9175 Other Parts Discussed in Thread: TPS23753AEVM-004 , TPS23753AEVM-001 Hi
Our customer has the following question for PMP9175 design.
1.
PMP9175 has secondary synchronous FET for high-efficiency operation.
Compared with un-synchronous…

Our customer is considering PMP9175 for their design and the following question is coming out.
1. There are two FET like following figure and Q5 is…
Hi Ahmed,
I think the DC/DC converter of TPS23753AEVM-001 design is for ~ 4W power when using a 12-V adapter.
For example, the flyback transformer (POE70P-50) used here has 0.65A peak current.
When the converter is operating at 12-V input and 4-W load…
Hi Chichin,
Sorry that I do not think we have reference circuit with 749119250. While you could look into the following reference designs and make some minor modifications.
PMP7355: 5V, 2A, Class 3,Cost-Optimized,Flyback Converter Reference Design for PoE…
Part Number: TPS23753A Other Parts Discussed in Thread: PMP9175 , TPS23755 , TPS23734 Hi,
I would like to ask you about the TPS23753A device. I'm looking at the PMP9175 schematic in a reference design. I want to use the secondary FET circuit (Q7) used…
Part Number: TPS23753A Other Parts Discussed in Thread: PMP9175 , TPS23755EVM-894 Hello,
I have used a variation of PMP9175 for a previous project with great success. I now have a requirement for a POE PD circuit which can provide an isolated +/-15V output…
Will,
PMP8454 can be operated with only one output. The lower feedback divider resistor value will need to change to provide a 5V output. Also, the loop compensation will need to be adjusted since the 3.3V output capacitance is no longer part of the loop…
David,
One last thing, do you think one of the EP7 or EP10 could work for the PMP9175: https://www.mouser.com/datasheet/2/336/-180276.pdf
