SP7122 Eval Board Schematic

_______________________________________________ USING THE EVALUATION BOARD

1) Powering Up the SP7120 or the SP7122 Circuit

The Evaluation Board can be powered from inputs ranging from 2.7 to 5.5Vin. All that is required

is to populate the LED location with desired LED and connect the source voltage to Vin and

GND. There is a jumper located on the PCB. The jumper needs to be set between center pin

and Vin to activate the part. If the jumper is left unpopulated the driver will be off due to the pull

down resistor on the enable pin.

For typical test results please refer to the data sheet.
