12. Test information
Figure 14
shows the test circuit used to measure power loss in the PIP202-12M. The
output voltage is measured using an averaging circuit. This eliminates losses in the
output inductor and the PCB tracks. The calculated power loss, using this method,
includes the losses in the Equivalent Series Resistance (ESR) of the input filter
capacitors. This must be subtracted from the total loss to give the net loss in the
PIP202-12M.
