The board contains a number of test points to allow evaluating the functions of the ZSPM4121 (see Figure 2.1 and section 4). It has a solid ground plane. Note: The default part number for the ZSPM4121 Under-Voltage Load Switch (U1 in the schematic in Figure 6.1) is ZSPM4121AI1Wxx, where xx refers to the factory-configured voltage threshold which is determined by the version of the ZSPM4121 Evaluation Board ordered. Contact ZMDI for available board versions. Note: The default configuration of the Evaluation Board is with the NPG pin pulled up to Vin via R1 and therefore R2 is unpopulated (NL designation in the schematic in Figure 6.1). If the application requires that NPG be pulled up to Vout, remove R1 and install R2.

The output of the Evaluation Board can be measured at the J2 screw terminal. Recommendation: Use J1 and J2 only for power connections. Use test points TP1 (Vin) and TP4 (Vout) as Kelvin connections for accurate voltage measurements (see Figure 2.1).
