IEEE 802.
3af-Compliant, High-Efficiency, Class 1/Class 2, Powered Devices with Integrated DC-DC Converter
General Description
The MAX5988A/MAX5988B provide a complete powersupply solution as IEEE® 802.
3af-compliant 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 p...
