产品概述
描述
The EVALPM8803-FLY is a demonstration board implementing an IEEE802.3at compatible interface together with a synchronous rectification flyback 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 for the main component (MOS, transformer, etc).
It is possible to connect auxiliary sources to one of the 2 jacks in the EVALPM8803-FLY like in real application design. In one case thanks to the PM8803 feature, prevalence of the auxiliary source can be guaranteed.
