LTC4264 High Power PD Interface Controller with 750mA Current Limit FEATURES DESCRIPTION Complete High Power PD Interface Controller The LTC 4264 is an integrated Powered Device (PD) in- IEEE 802.3af Compliant terface controller intended for IEEE 802.3af Power over Onboard 750mA Power MOSFET Ethernet (PoE) and high power PoE applications up to 35W. Complementary Power Good Outputs By including a precision dual current limit, the LTC4264 Flexible Auxiliary Power Options keeps inrush below the IEEE802.3af current limit levels Precision Dual Current Limit with Disable to ensure interoperability success while allowing for high Programmable Classi cation Current to 75mA power PD operation. The LTC4264 includes a eld-proven Onboard 25k Signature Resistor with Disable power MOSFET delivering up to 750mA to the PD load while Undervoltage Lockout maintaining compliance with the IEEE802.3af standard. Complete Thermal Overload Protection Complementary power good outputs allow the LTC4264 to Available in Low Pro le (4mm 3mm) DFN Package interface directly with a host of DC/DC converter products. The LTC4264 provides a complete signature and power APPLICATIONS interface solution for PD designs by incorporating the 25k signature resistor, classi cation circuitry, input current 802.11n Access Points limit, undervoltage lockout, thermal overload protection, High Power VoIP Video Phones signature disable and power good signaling. RFID Reader Systems PTZ Security Cameras and Surveillance Equipment The LTC4264 PD interface controller can be used along with a variety of Linear Technology DC/DC converter products to provide a complete, cost effective power solution for high power PD applications. The LTC4264 is available in the space-saving low pro le (4mm 3mm) DFN package. , LT, LTC and LTM are registered trademarks of Linear Technology Corporation.
