LTC4266 Datasheet - Linear Technology

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 .
