Analog Devices / Maxim Integrated MAXREFDES108 Power Supply Reference Design

Analog Devices MAXREFDES108 Power Supply Reference Design combines the PD controller (MAX5969A) and the step-down converter (MAX17505) on a 14.0mm (0.55in) x 55.9mm (2.2in) board. This Analog Devices reference design was created to meet the increasing demands for non-isolated Power over Ethernet (PoE) power solutions. These solutions efficiently convert high-voltage PoE power into 5V and 12V outputs. Each design was tested for load and line regulation, efficiency, and transient performance. The module accepts input voltages ranging from 36V to 57V and provides an output voltage of 12V with a current capacity of 1A. This board features a module architecture with through-hole pins for immediate board placement and accelerated prototyping.
