www.ti.com Test Summary
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 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.
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.
Four Fluke 75 multimeters, (equivalent or better)
Or: Three equivalent voltage meters and one equivalent current meter. The current meters must be
capable of measuring 2-A+ current.
