3 Description
The LP5817 is a 3-channel RGB LED driver. The
device has ultra-low operation current with 0.1μA
(typical) in shutdown mode, 0.15mA (typical) when
enable device and 0.2mA (typical) when illuminate
LEDs.
Both analog dimming and PWM dimming methods are
adopted to achieve powerful dimming performance.
The output current of each LED can be adjusted
with 256 steps from 0.1mA to 25.5mA or 0.2mA to
51mA. The 8-bits PWM generator enables smooth
and audible-noise-free dimming control for LED
brightness.
