Part Number: TPS23754 Other Parts Discussed in Thread: PMP7355 , PMP9175 , TPS23753A Hi Team,
Do we have PoE PD reference design can support Pos/Neg output power rail?
Below are customer's requirement.
only PD
±12V * 2 : +12V / 0.8A , -12V / 0.25A…
Part Number: TPS23753A Other Parts Discussed in Thread: PMP9175 , UCC24630 , TPS23757 , TPS2372-3EVM-757 , TPS23757EVM Is there a high efficiency reference design from TI using the TPS23753A?
We want to get the maximum output power out of standard PoE - class…
Hi Amina,
I recommend rechecking the app note. We use the same process in the design of our EVMs.
To clarify:
When you specify Vflyback_min = 36V, are you getting different transformer calculations than similar to the NA6223 specs? Be certain that…
Other Parts Discussed in Thread: PMP9175 Hello Darwin,
We implemented the PMP9175 into production. It seems to be sensitive to ESD causing the PoE controller to reset. Just touching/handling the board near diode / chip input can cause PoE to reset. Is…
Hello Steven and thank you for your question. There are two ways to answer it:
1) Manufacturing/purchasing perspective: From this view, there are no current plans to obsolete the LM5071. If you design it into a future product, shipments from your…
Hi Todd,
1. TPS23753A is newer IC without the secondary gate driver for a more cost effective soltuion.
2. We currently do not have an app note regarding different bridge topologies. Typically, diode bridges are used. When higher efficiency is needed …
Other Parts Discussed in Thread: TPS23750 , PMP9175 Hi,
I have question about TPS23750 Flyback-Converter heating issue,
in case of Zener D7( BZT52C18, ) and T2( C1174-AL: Coilcraft ),
These two components are over heating upto 100 'C at room temperature..…
Hello Sergey,
The TPS23758 EVM uses primary side regulation (PSR). This feature eliminates the need for a optocoupler + feedback network, but requires an additional winding on the transformer for the regulation. We have tested the Linkcomm transformer…
