5 Description (continued)

The LP503x device controls each LED output with a 12-bit PWM resolution at 29-kHz switching frequency. This

control helps get an intensity that decreases smoothly and stops audible noise. Having different color-mixing and

intensity-control registers makes writing the software code straightforward. When targeting fade-in, fade-out type

breathing effects, the global R, G, B bank control reduces the microcontroller loading significantly. The LP503x

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

on simultaneously.

The LP503x device has an automatic power-saving mode to get the ultra-low quiescent current. When channels

are all off for 30 ms, the device total power consumption is down to 10 µA, making the LP503x device a possible

alternative for battery-powered end equipment.
