Test Recommendations
To guarantee measurement accuracy, the following precautions should be observed:
1. Make all input and output voltage measurements at the board using the test
points provided (TP13 to TP16). This will eliminate voltage drop across the
line and load cables that can produce false readings.
2. Measure input and output current with series ammeters or accurate shunt
resistors. This is especially important when measuring efficiency.
3. Use a low-loop-inductance scope probe tip similar to the one shown below to
measure switching signals and input / output ripple to avoid noise coupling
into the probe ground lead. Input ripple, output ripple, and load transient
deviation are best measured near the respective input / output capacitors. For
more accurate ripple measurement, please see Enpirion App Note regarding
this subject.
4. The board includes a pull-up resistor for the POK signal and ready to monitor
the power OK status at clip lead marked POK.
5. This product has built-in short-circuit protection. If protection against an
overload condition is required, an appropriate external solution needs to be
used. Please refer to the Enpirion application note for further details on this
subject.
