EVALPM8803-FWD IEEE802.3at compliant demonstration kit with synchronous forward PoE converter
The EVALPM8803-FWD is a demonstration board implementing an IEEE802.3at compatible interface together with a self driven synchronous active clamp forward converter based on PM8803.
The board is designed to work up to 30 W, and with minimal changes the output voltage can be selected either 5 V or 3.3 V. For sake of flexibility, alternative footprint have been foreseen tor the main component (MOS, transformer, etc.).
It is possible to connect auxiliary sources to one of the 2 jacks in the EVALPM8803-FWD like in real application design. In one case thanks to the PM8803 feature, prevalence of the auxiliary source can be guaranteed.
