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
Is there any peripheral reference design for 802.3af 13W with TPS23754? Due to board space issues,
if there are…
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…
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: TPS23753A Other Parts Discussed in Thread: PMP9175 , CSD17527Q5A , CSD17551Q3A , CSD17579Q5A Hi
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…
