Equipment’s RequirementsTo start properly the NCP6878 evaluation kit, the

following equipments are required:• DC voltage power supply ( 2.5 V to 5.5 V, 4 A current

capability*)• Electronic load or SMU that can sink current to emulate

the load (0 A – 2.5 A range)• Banana cables to supply the Board and connect the load

• A personal computer with Windows XP or later**

• A−Male to mini B USB cable to connect the USBInterface Board to the PC**

* 4 A are required for 2.5 A max load operations in Boostmode

GETTING STARTED

The following procedure can be followed to first check theEvaluation Board status:• For NCP6878Vxxx and NCP6878A products:

1. Supply the evaluation board with 3.0 V between J6(VBAT banana plug, positive supply) and J10(GND banana plug, ground supply)

2. Check output voltage between TP3 (VOUT sensetest point) and a GND grip access (J3, J4 or J5)and refer to the following table:

Table 6.

Product Reference

Valid VOUT Range* (V)

Minimum Typical Maximum

NCP6878V330FCCT1G 3.267 3.3 3.333

NCP6878V315FCCT1G 3.118 3.15 3.182

NCP6878AFCCT1G 3.267** 3.3** 3.333**

* in the −1% to +1% range as specified** with R1 and R6 1% resistors and NCP6878AFCCT1G BOM default value

• For NCP6878PFCCT1G product:1. Supply the evaluation board with 3.0 V between J6

(VBAT banana plug, positive supply) and J10(GND banana plug, ground supply)

2. Connect the evaluation board to the USB InterfaceBoard with the ribbon cable and the USB InterfaceBoard to the PC with an A−Male to mini B USBcable.

3. Run the NCP6878P GUI software as depicted inthe NCP6878 GUI documentation

4. Check output voltage between TP3 (VOUT sensetest point) and a GND grip access (J3, J4 or J5)and refer to the following table:

Table 7.
