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) conv...
