TPE15018 Overview
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 TPE1501x fly-back converter is specifically designed with active clamp primary-side...
