3.3 Test Point Descriptions

Numerous test points are provided to access voltages and signals. All test points are designed for sensing voltages only and are not designed to carry large DC currents.

Table 3-3 Test Point Descriptions
Test Point Device Pin Description
TP1 VCCA This point can be used to measure IDDQ, when resistor R58 is removed.
TP2 VIO_IN This point can be used to measure IDDQ when resistor R65 is removed.
TP3, TP4, TP5 GND NA
TP6 FB_B3 External voltage monitor connection.
TP7 FB_B4
TP8 GPIO10 (SYNCCLKIN) Sync Clock input, up to 4.4 Mhz
TP9 SW_B1 Test Point for the switch node. Not populated to reduce EMI.
TP10 SW_B2
TP11 SW_B3
TP12 SW_B4
TP13 SW_B5
TP14 GND NA
