ezLINX™ iCoupler® Isolated Interface Development Environment Homepage
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 1 below to the UNREG_IN node of the circuit.
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 below in Figure 2.
