LTC4267CGN#PBF Products

The LTC4267CGN 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 LTC4267CGN integrates the 25kΩ 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. The precision dual level input current limit allows the LTC4267CGN 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 LTC4267CGN includes an onboard error amplifier and voltage reference allowing use in both isolated and nonisolated configurations.

The LTC4267CGN is available in space saving, low profile 16-pin SSOP or DFN packages.
