ISOSSFT2  
The Si3400 and Si3401 integrate all power management and control  
functions required in a Power-over-Ethernet (PoE) powered device (PD)  
application. The Si3400 and Si3401 convert the high voltage supplied over  
the 10/100/1000BASE-T Ethernet connection into a regulated, low-voltage  
output supply. The optimized architectures of the Si3400 and Si3401  
minimize the solution footprint, reduce external BOM cost, and enable the  
use of low-cost external components while maintaining high performance.  
The Si3400 and Si3401 integrate the required diode bridges and transient  
surge suppressors, thus enabling direct connection of ICs to the Ethernet  
RJ-45 connector. The switching power FET and all associated functions are  
also integrated. The integrated switching regulator supports isolated  
(flyback) and non-isolated (buck) converter topologies. The Si3400 and  
Si3401 support IEEE STD™ 802.3-2005 (future instances are referred to as  
802.3) compliant solutions as well as pre-standard products, all in a single  
IC. Standard external resistors connected to the Si3400 and Si3401 provide  
the proper 802.3 signatures for the detection function and programming of  
the classification mode. Startup circuits ensure well-controlled initial  
operation of both the hotswap switch and the voltage regulator. The Si3400  
and Si3401 are available in low-profile, 20-pin, 5 x 5 mm QFN packages.  
While the Si3400 is designed for applications up to 10 W, the Si3401 is  
optimized for higher power applications (up to approximately 15 W). See  
also “AN313: Using the Si3400/01 in High Power Applications” for more  
information.
