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 noise that you can hear. Having different color-
mixing and intensity-control registers makes writing the software code straightforward. When targeting fade-in,
fade-out type breathing effect, 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 ultralow quiescent current. When channels
are all off for 30 ms, the device total power consumption is down to 10 µA, which makes the LP503x device a
possible alternative for battery-powered end equipment.
