LTC4267-3 is a power over Ethernet IEEE 802.3af PD interface with integrated switching regulator. It combines an IEEE 802.3af compliant powered device (PD) interface with a 300KHz current mode switching regulator, providing a complete power solution for PD applications. It integrates the 25k signature resistor, classification current source, thermal overload protection, signature disable and power good signal along with an undervoltage lockout optimized for use with the IEEE-required diode bridge. This device provides an increased operational current limit, maximizing power available for class 3 applications. It is widely used in application such as IP phone power management, wireless access points, security cameras, power over Ethernet etc.
