POWER INPUT
An AC/DC desktop power supply is used to supply 7.5V input
to the barrel connector J1 on the ezLINX hardware. This supply
connects through a protection circuit as shown in Figure 11 to
the UNREG_IN node of the circuit.

3.3V POWER SUPPLY
The ADP1864 Constant Frequency Current-Mode Step-Down
DC-to-DC Controller is used with an external P-Channel
Mosfet to generate the regulated 3.3V Power Supply for the
ezLINX hardware. The circuit implementation of the 3.3V
power supply is shown in Figure 12.
