LTC4266 Datasheet (Linear Technology) - Quad IEEE 802.3at Power over Ethernet Controller

LTC4266, Quad IEEE 802.3at Power over Ethernet Controller

The LTC®4266 is a quad PSE controller designed for use in IEEE 802.3 Type 1 and Type 2 (high power) compliant Power over Ethernet systems.

External power MOSFETs enhance system reliability and minimize channel resistance, cutting power dissipation and eliminating the need for heatsinks even at Type
