Part Number: TPS2373 Other Parts Discussed in Thread: TPS23758
Dear Sir/Madam,
I am currently designing a product based on the ESP32 with Ethernet connectivity. The system will drive an 8-channel 5 V, 30 A relay module (each relay rated at 5 V, 30…
Part Number: DP83826AE Tool/software: My question is not specifically about the DP83826AE (I had to include a P/N to post), but about non-POE Ethernet PHYs in general.
This will seem as an unusual question, but my understanding of Ethernet PHY’s is…
Part Number: TPS23754 Tool/software: Hi, TI expert
A customer has an inquiry while developing a FIXED RFID terminal using TPS23754.
Q1) Is there a function in TPS23754 that can distinguish between POE / POE+ and notify?
There is a problem of controlling…
Part Number: TPS23731 Other Parts Discussed in Thread: TPS2378 , LM5116 Tool/software: I'm developing a passthru power management PCBA based on TPS23731 which will be a Class 4 PoE PD device.
The downstream system is a single board computer which already…
Part Number: TPS23754 Tool/software: Hello everyone,
Is there any 24V reference design for TPS23754? I want to design a 24V 30W PoE circuit and I am very new in this PoE world.
I've checked one reference design but I think the PoE transformer is now…
Hi Hanshraj,
From PoE aspect, HV isolation is required. For isolation purpose the ESD will ruin the 2kV isolation from the earth / chassis ground. But we have seen many customers added these diodes for ESD purpose when using > 57V bidirectional diodes…
Part Number: TPS23730 SCH_Schematic1_2025-11-12.pdf We have designed a PoE power card using the TPS23730 DC-DC controller, but the IC appears to be failing during the PSE-PD handshake stage. We need your support in identifying the root cause of this handshake…
Hi Leon,
LEON YAN said: the result is very different between QS and webbench designer.
Match the turns ratio between the webench and the QS, then also the inductance will match.
The ratio in the webench is 5.22, in the excel is 0.5.
In the QS…
Part Number: TPS23753A Tool/software: Hi,
Based on the previous thread discussing how to modify the design to achieve a 24V output, which can be found at the following link:
