LP3943 RGB/White/Blue 16-LED Fun Light Driver November 2003 LP3943 RGB/White/Blue 16-LED Fun Light Driver General Description LP3943 is an integrated device capable of independently driving 16 LEDs.
This device also contains an internal precision oscillator that provides all the necessary timing required for driving each LED.
Two prescaler registers along with two PWM registers provide a versatile duty cycle control.
The LP3943 contains the ability to dim LEDs in SMBUS/ I2C applications where it is required to cut down on bus traffic.
Traditionally, to dim LEDs using a serial shift register such as 74LS594/5 would require a large amount of traffic to be on the serial bus.
