2.1.8 List of Test Points, Jumpers, and Connectors

Table 2-1 lists the test point functions.

Table 2-1 Test Point Functions
Test PointNameDescription
TP1VIN_SVIN test point. Use this test point for efficiency measurements.
TP2SWSW node test point
TP3VOUT_EFFVOUT test point. Use this test point for efficiency.
TP4VINVIN test point at input terminal (T1)
TP5VOUTVOUT test point at output terminal (T2)
TP6, TP7PGNDPGND test points at input terminal (T1) and output terminal (T2)
TP8VCCVCC test point
TP9BODE-Use this test point for bode plot measurements.
TP10BODE+/Vout_REGVOUT test point. Use this test point for output regulation at remote sense and bode plot measurements.
TP11ENEN test point
TP12PGPG test point
TP13GOSGOS test point
TP14PGND_SPGND test point. Use this test point for efficiency measurements with VIN_S (TP1) test point.
TP15PGND_EFFPGND test point. Use this test point for efficiency measurements with VOUT_EFF (TP3) test point.
TP16PGND_REGPGND test point. Use this test point for output regulation at remote sense.
TP17SWSMB connector to measure SW node. When using this test point, set the scope for 50Ω termination. The combination of 50Ω termination and 450Ω series resistance creates a 10:1 attenuation.
TP18VOUTSMB connector to measure output voltage. When using this test point, set the scope for 1MΩ termination. When using 50Ω termination, a 2:1 divider is created.
TP19CNTLTest point connection to CNTL pin on J10 header
TP20CLKCLK test point
TP21/ TP22AGNDAGND test point
TP23PGNDPGND test point
TP24DATADATA test point

Table 2-2 lists the EVM jumpers.
