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.
