LTC4269IDKD-1#PBF Description

Short technical summary and product information.

The LTC4269IDKD-1#PBF is an integrated Powered Device (PD) controller and switching regulator designed for high power IEEE 802.3at and 802.3af applications. This controller is targeted for high efficiency, single and multi-output applications from 10W to 25W.

 

Key electrical specifications include a power rating of 25.5W, an input voltage range of 37.2V to 60V, and a maximum current of 1.35mA. It features an integrated synchronous flyback controller with isolated power supply efficiency greater than 92% and overall efficiency greater than 88%. The device includes undervoltage, overvoltage, and thermal protection, along with short-circuit protection with auto-restart.

 

This PoE controller operates within a temperature range of -40°C to 85°C. It is available in a 32-DFN (7x4) surface mount package with an exposed pad for enhanced thermal performance. The LTC4269IDKD-1#PBF supports both 1-event and 2-event classifications as defined by the IEEE.

 

Applications include VoIP phones with advanced display options, dual-radio wireless access points, PTZ security cameras, RFID readers, and industrial controls.
