An integrated power MOSFET switch eliminates the need for an external pass transistor, simplifying the BOM and reducing the PCB footprint for a 14-SOIC package. ## Supply range and current draw The controller operates from a 33 V to 66 V supply rail, covering the standard PoE voltage range including the 48 V nominal and accommodating the 57 V upper limit per 802.3af. Quiescent supply current is 2 mA typical, a low overhead for a PSE controller that must stay powered continuously on the switch or injector board. ## Temperature grade and environment Rated for 0°C to 70°C commercial temperature range — suitable for indoor enterprise switches, midspan injectors, and industrial Ethernet equipment in climate-controlled enclosures. ## Tape-and-reel vs tube packaging This variant (LTC4263CS#TRPBF) ships in Tape & Reel or Cut Tape, while the sibling LTC4263CS#PBF comes in a tube — the die, package, and electrical specs are identical; the difference is only the delivery format for pick-and-place vs bench assembly.","metaTitle":"LTC4263CS#TRPBF Analog Devices PoE PSE Controller, 15.4 W","metaDescription":"Analog Devices LTC4263CS#TRPBF single-channel PoE PSE controller, 15.4 W per 802.3af, internal switch, 14-SOIC.
