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.
