The MAX5986AETE+ from Analog Devices is a complete power-supply solution for IEEE 802.3af-compliant Class 1/Class 2 Powered Devices (PDs) in Power-over-Ethernet (PoE) systems. This integrated circuit combines a PD interface with an efficient DC-DC converter, reducing the need for external components.
The device features a wide input voltage range of 8.7V to 60V and supports up to 3.84W of input power. It offers protection against overload, output short circuit, output overvoltage, and overtemperature conditions. The integrated TVS diode provides protection against cable discharge events.
Designed for flexibility, the MAX5986AETE+ operates at fixed switching frequencies of 215kHz or 430kHz, with frequency foldback for improved efficiency at light loads. It includes features like hiccup-mode runaway current limit and a typical inrush current limit of 49mA. The device is available in a 16-TQFN (5x5) or 16-WQFN exposed pad package, suitable for surface mounting.
Key electrical specifications include a programmable output voltage range of 3.0V to 14V and an operating current of 3.6mA. The PD interface supports Class 1/Class 2 classification with a single external resistor and includes an intelligent Maintain Power Signature (MPS) compliant with IEEE 802.3af.
