Product Overview
The MAXREFDES98# is a 5V/2.5A non-isolated POE powered device power supply. MAXREFDES98# is a unique PoE module reference design, providing 5V at 2.5A (12.5W) from a 36V to 57V input. This design can be used for evaluation, design, prototyping and production. The circuit consists of two function blocks such as the PD controller and the step-down DC-DC converter. The PD controller section employs the MAX5969A and DC to DC power supply uses the MAX17505 4.5V to 60V input, 1.7A output, high-efficiency, synchronous, step-down DC-DC converter with internal compensation. The entire design delivers a peak efficiency of 86% with an input of 48V. Typical applications include lighting, IP cameras, sensors and non-isolated Ethernet equipment.
