1 Description
SPDCPOE05 is a power module specifically designed to provide an isolated, low-voltage
power source to a remote powered device (PD) in power over ethernet (PoE) applications.
SPDCPOE05 has full functional compliance with IEEE802.3af. It is designed to extract
power from Ethernet cable when sourced by power sourcing equipment (PSE) also
conforming to IEEE802.3af. SPDCPOE05 is rated 10 W and incorporate PD detection and
PD classification current signatures required for the PSE. The module is compatible with PD
classifications class 0. In addition to a fully integrated DC-DC converter, each SPDCPOE05
power module incorporates internal input diode bridges to support both data line and spare
line pair standard ethernet connections, a transient suppressor for input over-voltage
protection, and an EMI filter to ensure noise compatibility with Ethernet data signals. Other
features include: input under voltage lockout (UVLO), soft-start, over-current and short-
circuit protection.
