Product Details

The ADP5520 evaluation board allows the user to exercise the main features and functionality of the ADP5520 backlight driver with I/O expander IC. A daughterboard houses the actual IC and associated components for backlight driving. The daughter-board plugs into a larger motherboard that houses additional components for device configuration and stimulus. The evaluation board is powered via the USB port and is accompanied by a free register graphical user interface (GUI) that allows interaction with all internal settings of the ADP5520.
