It delivers up to 25.5 W to the load — the full power budget for a Class 4 PD under the PoE+ specification, meaning it can power devices like PTZ cameras, wireless access points, or thin clients that draw more than the 13 W limit of 802.3af. The internal switch is integrated, which simplifies the BOM by eliminating an external MOSFET and its associated gate drive components. The supply voltage range of 37.2 V to 60 V covers the full PoE bus voltage from the PSE output at the far end of a 100-meter cable run, including worst-case drop. ## Package, temperature grade, and layout notes The commercial-grade sibling LTC4265CDE#TRPBF is limited to 0°C to 70°C — a critical difference if the end product must survive a cold start. The part draws 1.35 mA from the PoE bus for its own operation, leaving the rest of the 25.5 W budget for the load. No auxiliary sense input is provided, so this controller cannot support an auxiliary power source — it is a pure PD controller, not a combined PD+DC/DC like the LTC4269 or LTC4278 peers. ## Active production and compliance posture No official second-source cross-reference exists — the LTC4265CDE#TRPBF is the same die in a commercial-temperature grade, not a functional alternative for industrial-rated designs.","metaTitle":"LTC4265IDE#TRPBF PoE+ PD Controller, 25.5 W, 12-DFN","metaDescription":"LTC4265IDE#TRPBF single-channel PoE+ PD controller, 25.5 W max, 37.2-60 V supply, -40 to 85°C.
