NCP1840 Description
NCP1840 8-Channel Programmable LED Driver The NCP1840 is a general purpose LED driver that allows for full programmability of eight separate LED channels through a simple I2C serial munication interface. The current through each of the channels can be up to 30 mA and is controlled via constant current regulation. Each channel has programmable Pulse−Width Modulation (PWM) control along with programmable current...
