The demonstration board is plugged vertically into the host board. Only one orientation is possible for correct plugin. The input and output power leads and an optional enable lead are wired into the host board connectors as shown in Figure 1. A mechanical toggle switch is also available on the host board for manual enabling and disabling of the demonstration board. The host board is configured by default for manual switch toggling of enable/disable. If an electrical control signal is preferred, this can be wired into the enable connector J2. However, in this case the zero ohm link connected in the R4 position must be removed and reconnected in the R1 position, which is vacant by default. A 5 V input to the enable pin disables the demonstration board and a 0 V or open circuit input signal causes the demonstration board to be enabled. Test pins are available on the host board, at the input, output, and enable pins, for the easy connection of scope probes. These wiring connections are depicted in Figure 1. The input connections should be wired as closely as possible to the power supply, using cable rated at 2 A or more. However, lead lengths of up to a meter or two are probably acceptable. If the leads are significantly lon...
