Power-Over-Ethernet Module
5.4. Power Classification
This is optional from the PSE and is used for power management. The Ag8200 allows the
current class to be externally programmed by connecting a resistor between the CP and
VIN- pins, see Figure 4. If no resistor is fitted the Ag8200 will default to Class 0, a full list of
programming resistor values are shown in Table 2.

5.5. DC/DC Converter
The Ag8200’s DC/DC converter provides a non-isolated regulated low ripple and low noise
output, that has built-in overload and short-circuit output protection, as well a built-in
thermal cut-off - see Table 1: Ordering Information for voltage and power ratings.
Because the Ag8200 series are non-isolated the +VDC output is (internally) connected to
the VIN+ input.
