MAXREFDES108#: Non-isolated 12V/1A PoE Powered Device Power Supply (MAXREFDES108)

To meet the increasing demands for non-isolated Power over Ethernet (PoE) power solutions, Maxim has developed innovative, non-isolated PoE powered device (PD) power solutions. These non-isolated PoE power solutions efficiently convert high voltage PoE power into 5V and 12V outputs, respectively. Each design was tested for load and line regulation, as well as efficiency and transient performance. As with all Maxim reference designs, the BOM, schematics, layout files, and Gerber files are all available and may be downloaded from the Design Resources tab. In addition, boards are available for purchase. These boards feature a module architecture, with through-hole pins for immediate board placement and accelerated prototyping.

MAXREFDES108# combines the PD controller and the step down converter on a 14.0mm (0.55in) x 55.9mm (2.2in) board. The module accepts input voltages ranging from 36V to 57V, and provides an output voltage of 12V with current capacity of 1A.

For initial evaluation, Maxim also provides an evaluation board, MAXREFDES98EV#. This board features RJ45 connectors for quick testing with sourced power.
