Part Number: TPS2378 Other Parts Discussed in Thread: PMP11257 Tool/software: Hi, I am trying to achieve 48V on Vdd with reference to RTN. I have added a bulk capacitance of 47uF from Vdd to RTN.
The Vdd voltage kept on resetting from 46V down to 0V…

现用Ti的TPS2378做交换机的 PD接口芯片,按下面原理图做成PD设备。接PSE设备后,无法给该PD设备供电(PSE设备是好的,可以给摄像机供电),量得PD接口处电压在DC3V左右。请分析下原理图有啥问题!
We are currently using Ti's TPS2378 as the PD interface chip and making the PD device according to the following…
Part Number: TPS2378 Tool/software: Hi
The customer's PSE has LLDP protocol, so it should be supported by PD as well. Do you have any PD IC available? If not, how do I configure the circuit?
Thanks
Part Number: TPS2378 Tool/software: Hi,
I am considering a circuit configuration using TPS2378, based on page 7 of the application note "SLVA306A". The input voltage is 9-36V. Could you please comment if there are any points I should be careful about…
Part Number: TPS2378 Hi engineer:
I have some problem about TPS2378:
1. When using TPS2378 under light load (less than or equal to 11mA), 2.46S restart interval will appear, and the load greater than 11mA will be normal;
2. With load, the ground…

Hi, this is my first post here. I have some experience designing around Arduinos and ESP32's, but this is my first design with PoE and the TPS2378.
Basically, i've been told that jacks with CTs on the "board-side" are useless…
Part Number: TPS2378 Do you have a recent app note or white paper on how to do this? There was mention of a presentation here: https://www.ti.com/product/TPS2378?keyMatch=TPS2378&tisearch=search-everything&usecase=GPN-ALT Perhaps you can send me…
Part Number: TPS2378 Dear TI support,
TPS2378 datasheet contains 2 different package drawings: DDA0008A on pages 31-33, DDA (R-PDSO-G8) on pages 34-36. These drawings have differences. So I need to know what DDA package TI really uses for TPS2378.
TI offers…
Part Number: TPS2378 Hi Team,
(1) For 802.3at TYPE-2 specification, it is recommended to add an external MOSFET (one more level of soft start) at 25W, and the capacitance should not exceed 47uF. Because the larger the capacitance value is, the larger the…
