Test Summary
This procedure details how to configure the evaluation board. On the test procedure, the following naming
conventions are followed. See
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.
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.
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 20 V at 2 A is required.
Power Supply #2 (PS#2): a power supply capable of supplying 5 V at 1 A is required.
Power Supply #2 (PS#2): a power supply capable of supplying 5 V at 1 A is required.
A 10-V (or above), 2-A (or above) electronic load that can operate at constant current mode.
A 10-V (or above), 2-A (or above) electronic load that can operate at constant voltage mode.
