IEEE 802.3af-pliant, High-Efficiency, Class 1/Class 2, Powered Devices with Integrated DC-DC Converter
General Description
The MAX5991A/MAX5991B provide a plete powersupply solution as IEEE® 802.3af-pliant Class 1/ Class 2 Powered Devices (PDs) in a Power-over-Ethernet (PoE) system. The devices integrate the PD interface with an efficient DC-DC converter, offering a low external part count PD solution. The devices also include a low-dropout regulator, MPS, sleep, and ultra-low power modes. The PD interface provides a detection signature and a Class 1/Class 2 classification signature with a single external resistor. The PD interface also...
