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 | NC | Internal Connection. Do not connect to this pin. |
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. |
TYPICAL SYSTEM DIAGRAM
Add 20uf / 25V capacitance at the output,This will reduce the ripple and noise to typically 140mVp-p. 24V@1A.
optional external lc filter for lower ripple and noise,This will reduce the ripple and noise to typically 40mVp-p. 24V@1A.
