Part Number: TPS2377-1
Hi,
We have designed PoE powered device using TPS2377-1. The device will operate on 3.3V/200mA(max). since the device is low powered and portable, we did not use any magnetics and isolation transformer.
Request you to review…
Matt,
Take a look at the snapshot from the TPS2377 datasheet. The formula is for MAX capacitance not "recommended cap". You do not have to use 1.67mF. It just needs to be lower than that and greater than 5uF.
Let us know if anything else is unclear…
Part Number: TPS2377-1 Dear sir,
Can You arrange the samples for TPS2377-1.
We Ordered the IC's, it will not receive on the expecting time. But we need to show the demo urgently. we need to test the circuit. We don't have IC now. So please arrange…
Part Number: TPS2377-1 Dear sir/Madam,
I need to design the PoE PD module for the 12W application. I did the design using TPS2377-1.
I have doubt about the Mode A and mode B types of transmission in PoE communication.
How do I make the circuit compatible…
Part Number: TPS2377-1 Dear Sir,
I test the PoE PD circuit built by using TPS2377-1. but if I connect with PSE device, the power LED of the PSE device (PoE Injector) was blinking. I attach the Schematic circuit also.

Is there an 802.3at TYPE 2 CLASS2 or 802.3bt capable IC that is PIN to PIN compatible with the TPS2375?

Hi Chaojin,
The falling UVLO of 32V allows for enough margin for operation at 37V (as long as the rising UVLO is met during startup).
If you would like a PD for type 1 operation, I would recommend these:

Hello,
The UCC3806 is a dual output controller though it can be used in a flyback where only one of the outputs are used to drive the switch it might be better to choose a single output controller. Look at page 46 of the attached under General Purpose…
