4 Description (continued)

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

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

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 30ms, the device total power consumption is down to 10µA, which makes the LP50xx

device a potential choice for battery-powered end equipment.
