Description
General part information
LTC4267-1 Series
The LTC4267-1 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 LTC4267-1 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. The LTC4267-1 provides an increased operational current limit, maximizing power available for class 3 applications.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 LTC4267-1 includes an on-board error amplifier and voltage reference allowing use in both isolated and nonisolated configurations.The LTC4267-1 is available in a space saving, low profile 16-pin SSOP package.ApplicationsIP Phone Power ManagementWireless Access PointsSecurity CamerasPower over Ethernet
