The LP3942 is an integrated stand-alone RGB LED controller with a high efficiency and low noise programmable 1.5x and 2x charge pump. The RGB LEDs are controlled through the low voltage SPI interface. RGB programmability allows unique color and brightness control with both RGB outputs. The color control has preselected color settings for color blending. The LED current control is done using constant current sinks that can be also used as switches. The nonoverlapping RGB output PWM control minimizes the input noise.
