Typical Connections
Figure 4 illustrates the typical input supply and output load connections required to power the PI3741‑x0
evaluation board. The test points on the right side of the board provide access to key nodes used to
assess the board's performance. The jumper "JGP" provides an access point that allows the user to add
a small signal in the feedback loop to make Gain/Phase measurements. The jumper J5 will connect the
IMON output signal to the positive input of the general purpose amplifier, allowing this signal to be
scaled. The J6 jumper will disable the converter when connected.
JVIN is an unpopulated "Johnson Jack" location that may be used to measure input ripple voltage.
