5 Description (continued)

The LP50xx device controls each LED output with a 12-bit PWM resolution at 29-kHz switching frequency, which

helps achieve a smooth dimming effect and eliminates audible noise. The independent color mixing and

brightness control registers make the software coding straightforward. When targeting a fade-in, fade-out type

breathing effect, the global R, G, B bank control reduces the microcontroller loading significantly. The LP50xx

device also implements a PWM phase-shifting function to help reduce the input power budget when LEDs turn

on simultaneously.

The LP50xx device implements an automatic power-saving mode to achieve ultralow quiescent current. When

channels are all off for 30 ms, the device total power consumption is down to 10 µA, which makes the LP50xx

device a potential choice for battery-powered end-equipments.
