Analog Devices Inc.
The LTC4267 combines an IEEE 802.3af compliant Powered Device (PD) interface with a current mode switching regulator, providing a complete power solution for PD applications. The LTC4267 integrates the 25k? signature resistor, classi?cation 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. The precision dual level input current limit allows the LTC4267 to charge large load capacitors and interface with legacy PoE systems.The current mode switching regulator is designed for driving a 6V rated N-channel MOSFET and features programmable slope compensation, soft-start, and constant frequency operation, minimizing noise even with light loads. The LTC4267 includes an onboard error ampli?er and voltage reference allowing use in both isolated and nonisolated con?gurations.The LTC4267 is available in space saving, low pro?le 16-pin SSOP or DFN packages.Applications IP Phone Power Management Wireless Access Points Security Cameras Power over Ethernet
