LTC4266IUHF - Brand New Linear Technology Power Over Ethernet Controllers
-
Description
The LTC4266IUHF is a quad PSE controller designed for use in IEEE 802.3 Type 1 and Type 2 (high power) compliant Power over Ethernet systems. It features external power MOSFETs to enhance system reliability, minimize channel resistance, and cut power dissipation. This eliminates the need for heatsinks even at Type 2 power levels. The LTC4266IUHF is also compatible with the IEEE standard and can be used at very high power levels. It has 80V-rated port pins to provide robust protection against external faults.
