FEATURES  
DESCRIPTIO  
Complete Power Interface Port for IEEE 802®.3af  
The LTC®4267-1 combines an IEEE 802.3af compliant  
PoweredDevice(PD)interfacewithacurrentmodeswitch-  
ing regulator, providing a complete power solution for PD  
applications. The LTC4267-1 integrates the 25k signature  
resistor, classification current source, thermal overload  
protection, signaturedisableandpowergoodsignalalong  
with an undervoltage lockout optimized for use with the  
IEEE-required diode bridge. The LTC4267-1 provides an  
increased operational current limit, maximizing power  
available for class 3 applications.  
Powered Device (PD)  
Onboard 100V, UVLO Switch  
Precision Dual Level Inrush Current Limit  
Integrated Current Mode Switching Regulator  
Onboard 25k Signature Resistor with Disable  
Programmable Classification Current (Class 0-4)  
Thermal Overload Protection  
Power Good Signal  
Integrated Error Amplifier and Voltage Reference  
Low Profile 16-Pin SSOP Package  
The current mode switching regulator is designed for  
driving a 6V rated N-channel MOSFET and features pro-  
grammable slope compensation, soft-start, and constant  
frequency operation, minimizing noise even with light  
loads. The LTC4267-1 includes an onboard error amplifier  
and voltage reference allowing use in both isolated and  
nonisolated configurations.
