Complete Power Interface Port for IEEE 802®.3af  
Powered Device (PD)  
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.
