Maxim MAX5988A/B Class 1/2 Powered Devices

Maxim Integrated MAX5988A / MAX5988B IEEE®802.3af-compliant Class 1 / Class 2 Powered Devices (PDs) provide a complete power-supply solution in a Power-over-Ethernet (PoE) system. MAX5988A and MAX5988B integrate the PD interface with an efficient DC-DC converter, offering a low external part count PD solution. These 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 provides an isolation power MOSFET, a 60mA (max) inrush current limit, and a 321mA (typ) operating current limit. The integrated step-down DC-DC converter uses a peak current-mode control scheme and provides an easy-to-implement architecture with a fast transient response.
