LTC4269IDKD-1#TRPBF

LTC4269-1 is an integrated powered device (PD) controller and switching regulator intended for high power IEEE 802.3at and 802.3af applications. This device is targeted for high efficiency, single and multioutput applications from 10W to 25W. By supporting both 1-event and 2-event classifications, as defined by the IEEE, this device can be used in a wide range of product configurations. The device's synchronous, current mode, flyback controller generates multiple supply rails in a single conversion step providing for the highest system efficiency while maintaining tight regulation across all outputs. A true soft-start function allows graceful ramp-up of all output voltages. It is widely used in application such as VoIP phones with advanced display options, dual-radio wireless access points, PTZ security cameras, RFID readers, industrial controls etc.
