... PoE-VOICE-RD 2.1. Power Section The PoE-VoIP-EB Reference Design Board contains a Power Over Ethernet circuit based on the Si3400. In addition to performing all the functions required by the IEEE 802.3af specification, the Si3400 contains a switching regulator capable of regulating many voltages including 5 or 3.3 V. Since the Si3400 output will be passed through an LDO (used for the auxiliary 9 V supply output was chosen ...
