Detailed Product Description

Quick Detail:

 

Power over Ethernet IEEE 802.3af PD Interface with Integrated Switching Regulator

 

 

Description:

 

The LTC®4267-1 combines an IEEE 802.3af compliant Powered Device (PD) interface with a current mode switching regulator, providing a complete power solution for PD applications. The LTC4267-1 integrates the 25k signature resistor, classifi cation current source, thermal overload protection, signature disable and power good signal along

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.

The current mode switching regulator is designed for driving a 6V rated N-channel MOSFET and features programmable slope compensation, soft-start, and constant frequency operation, minimizing noise even with light loads. The LTC4267-1 includes an onboard error amplifi er

and voltage reference allowing use in both isolated and nonisolated confi gurations.

The LTC4267-1 is available in a space saving, low profile 16-pin SSOP package.

 

 

Applications:

 

■ Complete Power Interface Port for IEEE 802®.3af 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 Classifi cation Current (Class 0-4)

■ Thermal Overload Protection

■ Power Good Signal

■ Integrated Error Amplifi er and Voltage Reference

■ Low Profi le 16-Pin SSOP Package
