The Document "UG333: Class 4 Isolated Evaluation Board for the Si34061" refers to Application Note 1130.
Where can I find the “AN1130: Using the Si3406/Si34061/Si34062 PoE+ and Si3404 PoE PD Controller in Isolated and Non-Isolated Designs”?
Tank you and best regards
We have designed a PoE system for 24V,15W with SI3402-B-GM controller. We have customized the design to 24V since the EVB is 5V.
We would like to review our schematics by Silabs team and provide valuable suggestions.
In the Application notes and other areas, it is said to mail your queries to PoEinfo@silabs.com
This is what I received on sending mail
We are in last quarter of the design phase and we need to finalize the design. Where should I contact get the schematics review done??
Please respond asap
We are using SI3402-B-GM controller for a production of 1 million devices. We would like to clarify whether this product has support for more than 5 years. Please respond asap.
We would like to use Si3404 for one of our PoE application. I am referring to Si3404-ISO-FB EVB schematics and BOM. But, I am not able to get the datasheet of the transformer, TOEP13-0155S1 used in the design. Could you please send the datasheet of the transformer. Or is there any alternate Coilcraft or well known Transformer which can be used?
I bought the Si34061ISOC4-KIT two weeks ago. I can't find any datasheet or information for CX-9642 made by Coilcraft. Cloud you help support the datasheet?
Is there any other transformer can compatible.

I want to design a PoE non-isolated DC/DC converter using SI3402. The Input supply from PoE is 6.5W and the output load is maximum 3W with 3.3V output. In normal working condition, output current is around 0.2A. I am referering AN956 application note for my design. To run in continious mode for 0.2A output current, I have selected 100uH inductor. Apart from this is there any changes required?
Due to my board dimension constrain, It's difficult to have 560uF or 1000uF output capacitor, is there any other way to reduce the capacitor value. As per application note AN956, the output volatge variation for a load step of 10mA will be 0.32V for 1000uF (correct me if I am wrong), is there any way to reduce the output ripple?
I have implemented for firt time your PoE driver Si3402-C (isolated variant, in attachment is schematic) how ever I could not make it work correctly. The main problem is that on SWO I can see 15kHz pulses and not 350kHz. Then the output voltage is not stable and the output voltage depends on current load. It seems that the loopback is not working properly. How ever in datasheet is not closer description about the ERROUT pin so I dont know how to check if it is working properly or not. Any ideas what to check?
I need to design POE+ PSE endpoint , please suggest some IC which require minimum hardware and firmware. Also let me know if any reference circuit design any eval board available?
