概述

The TPE15017 is a monolithic power over ethernet (PoE) powered device (PD) with integrated PD interface and flyback power converter. The device supports IEEE 802.3af standard interface and targets for small-size 13-W isolated PoE applications.

The PD interface has all the functions of IEEE 802.3af, including detection, classification, inrush current, operation current limit, and 100-V hot-swap MOSFET.

To achieve small size and high-switching frequency, the TPE15017 fly-back converter is specifically designed with active clamp primary-side regulation (PSR) fly-back topology. TPE15017 can also be set in secondaryside regulation (SSR) active clamped fly-back topology, which can get best regulation through opto-coupler from secondary side.

The TPE15017 automatically sinks 15-mA pulse current as the maintain power signature in light load condition to maintain the connection with the PSE equipment and turns off the MPS current when the load current is above the MPS threshold.

The TPE15017 is available in 3mm x 4mm QFN-19 package.
