LT4275CHMS#TRPBF DescripTion

The LT®4275 is a pin-for-pin compatible family of IEEE802.3 and LTPoE++ powered device (PD) controllers.The LT4275A employs a proprietary LTPoE++ classificationscheme, delivering 38.7W, 52.7W, 70W or 90W of powerat the PD RJ45 connector. The LT4275A is fully compat-ible with IEEE 802.3. The LT4275B is an IEEE 802.3atcompliant, Type 2 (PoE+) PD delivering up to 25.5W. TheLT4275C is an IEEE 802.3af compliant, Type 1 (PoE) PDdelivering up to 13W.The LT4275 internal charge pump provides an N-channelMOSFET solution, eliminating a larger and more costlyP-channel MOSFET. A low RDS(ON) MOSFET also maxi-mizes power delivery and efficiency, reduces power andheat dissipation, and eases thermal design. Startup inrushcurrent is adjustable with an external capacitor. The LT4275also includes a power good output, on-board signatureresistor, undervoltage lockout, and thermal protection. TheLT4275A/LT4275B drives a single opto-coupler to indicatethe power level of the attached PSE. Pin-selectable sup-port for non-standard low voltage operation is provided.Auxiliary power override is supported with the AUX pin.The LT4275A can be configured to support all possibleLTPoE++, 802.3at and 802.3af power levels with externalcomponent changes.
