Pin 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 Detect Output	AT Detect Output. This pin indicates if an IEEE802.3at PSE is supplying power to the DP5400;
4	NC	Internal Connection. Do not connect to this pin.
5	-VDC	Negative DC Output. This pin provides the negative regulated output from the Ag5300 and is internally connected to pin 8.
6	+VDC	Positive DC Output. This pin provides the positive regulated output from the DP5300.
7	ADJ	Output Adjust. The output voltage can be adjusted from its nominal value, by connecting an external resistor from this pin to either the +VDC pin or the -VDC pin.
8	-VDC	Negative DC Output. This pin provides the negative regulated output from the Ag5300 and is internally connected to pin 5.
