GENERAL DESCRIPTION

The evaluation system is composed of a motherboard, daughter-
board, and LED subboard. The motherboard provides the I
signals from the PC USB port and generates the I/O voltages
and digital high and low signals for the daughterboard. For
overtemperature measurement, the daughterboard can be either
plugged directly into the motherboard or connected to the
motherboard via a ribbon cable.
PLEASE SEE THE LAST PAGE FOR AN IMPORTANT
WARNING AND LEGAL TERMS AND CONDITIONS.
ADP1650 Evaluation Board
The motherboard features a 3.3 V regulator and 2.8 V/1.8 V
regulators for VDDIO. The daughterboard contains jumpers
and test points for easy evaluation of the flash driver integrated
circuit (IC).
Operating details are provided in the
which should be consulted in conjunction with this evaluation
board user guide.
