2 DC­DC Converters, 5 LDOs
and a Triple Input 10 bits
ADC Evaluation Kit Manual
The NCP6925EVK evaluation kit is a full assembled
circuit board for evaluation and test of the NCP6925. This
document provides documentation, test procedure and
equipment set-up for the complete evaluation of the
NCP6925. The NCP6925EVK comes with one NCP6925
evaluation board, 1 MCU board for I
associated cables.
General Description
The NCP6925 integrated circuit is part of the
ON Semiconductor mini power management IC family
(PMIC). It is optimized to supply battery powered portable
application sub-systems such as camera function,
microprocessors. This device integrates 2 high efficiency
