Description：

The RT30P03M series of modules are designed to extract power from a conventional

twisted pair Category 5 Ethernet cable, conforming to the IEEE 802.3af and IEEE 802.3at Power-over-Ethernet(PoE) standard.

The RT30P03M signature and control circuit provides the PoE compatibility signature and

power classification required by the Power Sourcing Equipment (PSE) before applying up

to 30W power to the port.

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.

RT30P03M Pin Description:

Pin #	Name	Description
1	VIN+	POE Direct Input +. This pin connects to the positive (+) output of the POE input bridge rectifiers.
2	VIN-	POE Direct Input -. This pin connects to the negative (-) output of the POE input bridge rectifiers.
3	AT-DET-	AT Detect Output. This pin indicates if an IEEE802.3at PSE is supplying power to the RT5300.
4	CAP-	Internal cap-, If need Match Dynamic load ,connecting external cap- ,22uf-100uf 63v-100v OR NC
5	-VDC	DC Return. This pin is the return path for the +VDC output.
6	+VDC	DC Output. This pin provides the regulated output from the DC/DC converter.
7	ADJ	Output Adjust. The output voltage can be adjusted from is nominal value, by connecting an external resistor from this pin to either the +VDC pin or the -VDC pin.
8	-VDC	DC Return. This pin is the return path for the +VDC output.

Absolute Maximum Ratings
