LINEAR TECHNOLOGY LT4275AIDD#PBF 芯片, 以太网供电器, IEEE802.3, LTPOE++, 90W, 10DFN
The is a pin-for-pin compatible family of IEEE 802.3 and LTPoE++ Powered Device PD Controller employs a proprietary LTPoE++ classification scheme, delivering 90W of power at the PD RJ45 connector. The LT4275A is fully compatible with IEEE 802.3. The LT4275 internal charge pump provides an N-channel MOSFET solution, eliminating a larger and more costly P-channel MOSFET. A low RDSON MOSFET also maximizes power delivery and efficiency, reduces power and heat dissipation and eases thermal design. Startup inrush current is adjustable with an external capacitor. The LT4275 also includes a power good output, on-board signature resistor, undervoltage lockout and thermal protection. It drives a single opto-coupler to indicate the power level of the attached PSE. Pin-selectable support for non-standard low voltage operation is provided.
