SOFTWARE INSTALLATION
Double click on NCP6951_setup.exe file. Follow the
instructions set−up.
It is recommended to copy the NCP6951_setup.exe to a
local directory: If eval kit is already installed, a simple
double click on NCP6951.exe will launch the GUI.
Important notice: In order to properly install drivers and
software, please launch NCP6951_setup.exe file before
connects the MCU board.

NCP6951EVK
QUICK CONFIGURATION
Power Supply
Load
NCP6951 requires at least 1 external power supply:
Vbat (J2) : supply between 2.5V to 5.5V.
DCDCx Converters
An electronic load or passive load can be connected
between J7 and J8 for DCDC1.
Jumpers Configuration
The HWEN, FLEN and FLSEL jumpers are configured
by default to work with the ON Smiconductor I2C interface
board.
S103, S104 and S106 shunt are soldered to use only one
power supply for the DCDCs, LDOs and FLASH.
S101, S102 and S110 are soldered to close the loop of the
inside buck and boost converter. To measure the current,
user has to unsolder the jumper and use SH1, SH2 or SH4.
LDOx Regulators
An electronic load or passive load can be connected
between J9 and J8 or J14 for LDO1, between J10 and J8 or
J14 for LDO2, J11 and J8 or J14 for LDO3, J12 and J8 or J14
for LDO4, J13 and J8 or J14 for LDO5.
FLASH LED Driver
Evaluation board is delivered with D1 or D2 soldered.
