Product Overview

The MAXREFDES108# is a 12V/1A non-isolated POE powered device power supply. MAXREFDES108# is a unique PoE module reference design, providing 12V at 1A (12W) 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 90% with an input of 48V. Typical applications include lighting, IP cameras, sensors and non-isolated Ethernet equipment.
  • Compact and flexible
  • Minimal external components
  • Robust operation in adverse environments
  • 12W output capacity and ±3% output accuracy
