RT9600 3.3V 5V 12V 24V
The RT9600 series of modules are designed to extract power from a conventional twisted pair Category 5 Ethernet cable, conforming to the IEEE 802.3af Power-over-Ethernet(PoE) standard.
The RT9600 signature and control circuit provides the PoE compatibility signature and
power classification required by the Power Sourcing Equipment (PSE) before applying up
to 15W power to the port. The RT9600 provides a Class 0 signature.
The DC/DC converter operates over a wide input voltage range and provides a regulated
output. The DC/DC converter also has built-in short-circuit output protection.

Note 1: Typical figures are at 25°C with a nominal 48V supply and are for design aid only. Not Guaranteed
2: The output ripple and noise can be reduced with an external filter, see application note.
3: Continuous short circuit duration is applicable at 25'C ambient temperature in free air. At higher temperatures or with restricted
airflow (e.g. in a sealed enclosure) the duration will need to be limited to avoid overheating.
