Part Number: TPS23753A Other Parts Discussed in Thread: PMP7355 , , TL431 , Tool/software: Hello,
I designed a PoE powered device using TPS23753APWR , based on the PMP7355 reference design . The main difference is that I use a different transformer…
Another question that I forgot to ask, in PMP7355, D4 is connected to the low side (GND) of the secondary winding, I have seen in the datasheet for TPS23753a that it is connected in series with the output, the high side of secondary winding, why is that…
Other Parts Discussed in Thread: PMP7355 Hi,
We want to use PMP7355 Reference Design for low cost and small size.
We want to operate this EVM at 4.2V so we change the value of R24. 18.51 kohm will be selected.
Can we operate this EVM at 11W output…
Part Number: TPS23753A Other Parts Discussed in Thread: PMP7355 , PMP9175 , Hi,
I would like to design PoE PD 802.3at Type-1 class-2, 7W and suppose using TPS23753A solution. Do you have any suggestion Flyback transformer part can provide to me for…
Hi Daniel, Here are my recommendations - Reduce R542 to 10ohms - PMP7355 is a tested & highly optimized solution, so consider copying the component values for the feedback & current sense circuits. On PMP7355, that would be R18, R20, C21, R28, R23, R22…
Part Number: TPS23758 Other Parts Discussed in Thread: TPS23755 , PMP7355 Hi Expert,
My customer is using TPS23758 in their IP CAM product. They need the 5V/ single output. Based on their request, we have proposed the TPS23758 to them.
Recently…
Hi Sammi, We suggest using TPS23753A instead since It will be supported longer. Here are some tested & optimized 5V 13W flyback reference designs that fit their requirements: PMP9175 - Sync Rectifier Flyback PMP7355 - Diode Rectifier Flyback Thanks, Tom…
