5. Conclusion
The Si3400 is designed for a maximum input power of
12.95 W, which is consistent with the IEEE 802.3af
standard. Taking into account cost-effective dc-dc
converter
implementations
and
high-efficiency
performance, this results in a maximum output power of
10 W.
For applications requiring more than 10 W output power,
the Si3401 features an increased hot swap switch
current limit of 470 mA (minimum). This allows the
Si3401 to support 14 to 16 W applications with a small
number of BOM modifications and by selecting an
appropriate power supply topology.
Si3401-EVB and Si3401ISO-EVB application boards
are available with these recommendations. Complete
circuit and performance data are documented in the
corresponding user’s guides.
