MAX5986A–MAX5986C/ MAX5987A EVALUATION KIT AVAILABLE IEEE 802.3af-Compliant, High-Efficiency, Class 1/Class 2, PDs with Integrated DC-DC Converter General Description The MAX5986A–MAX5986C/MAX5987A provide a complete power-supply solution as IEEE® 802.3afcompliant 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 MAX5987A includes a low-dropout regulator and the MAX5986A– MAX5986C include 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.
