This procedure details how to configure the evaluation board. On the test procedure, the following naming
conventions are followed. See the schematic for details.
VXXX External voltage supply name (VIN, VBAT, VOUT)
LOADW: External load name (LOADR, LOADI)
V(TPyyy) : Voltage at internal test point TPyyy. For example, V(TP1) means the voltage at
TP1.
V(Jxx): Voltage at jack terminal Jxx.
V(TP(XXXXX)): Voltage at test point “XXXXX”. For example, V(ACDET) means the voltage at
the test point which is marked as “ACDET”.
V(XXX, YYY): Voltage across point XXX and YYY.
I(JXX(YYY)): Current going out from the YYY terminal of jack XX.
Jxx(BBB): Terminal or pin BBB of jack xx
Jxx ON : Internal jumper Jxx terminals are shorted
Jxx OFF: Internal jumper Jxx terminals are open
Jxx (-YY-) ON: Internal jumper Jxx adjacent terminals marked as “YY” are shorted
Measure: A,B Check specified parameters A, B. If measured values are not within specified
limits the unit under test has failed.
Observe A,B Observe if A, B occur. If they do not occur, the unit under test has failed.
Assembly drawings have location for jumpers, test points and individual components
Power Supply 1 (PS 1): a power supply capable of supplying 10 V at 2 A is required.
