LTC4269CDKD-1#TRPBF 说明EEE 802.3at PD with Synchronous No-Opto Flyback Controller具同步 No-Opto 反激式控制器的 IEEE 802.3at PDThe LTC®4269-1 is an integrated Powered Device (PD)controller and switching regulator intended for high power IEEE 802.3at and 802.3af applications. The LTC4269-1 is targeted for high ef? ciency, single and multioutput applications from 10W to 25W. By support- ing both 1-event and 2-event classi? cations, as de? ned by the IEEE, the LTC4269-1 can be used in a wide range of product con? gurations. The LTC4269-1 synchronous, current mode, ? yback con- troller generates multiple supply rails in a single conversion step providing for the highest system ef? ciency while main- taining tight regulation across all outputs. The LTC4269-1 includes Linear Technology’s patented No-Opto feedback topology to provide full IEEE 802.3 isolation without the need of an opto-isolator circuit. A true soft-start function allows graceful ramp-up of all output voltages. All Linear Technology PD solutions include a shutdown pin to provide ? exible auxiliary power options. The LTC4269-1 can accommodate adaptor voltages from 18V to 60V and supports both PoE or aux dominance options. The LTC4269-1 is available in a space saving 32-pin DFN package.
