Overview
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 communication 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 control, allowing for very flexible, optimized LED brightness and color control.
Logarithmic output current levels are achieved to best accommodate natural eye viewing.
A QUAD−MODE® charge pump allows for higher forward voltage LEDs and/or multiple LEDs in series per channel to be driven with a low−voltage supply.
This makes the NCP1840 capable of efficiently driving LEDs in applications that are running off of low−voltage processor supply levels along with battery−powered applications.
Few external components are required making this a very cost−effective solution for multi−channel LED driving.
