The MCP1643 RGB LED Driver Demonstration Board is used to evaluate and demonstrate Microchip Technology’s MCP1643 product. This board demonstrates the MCP1643 in a boost LED driver application supplied by one AA battery, or from an external voltage source, which drives each color of the RGB LED separately at a frequency of 70Hz with a constant current of 350mA. The RGB LED is driven by a microcontroller with 3 PWM signals and by modifying the duty cycle using individual potentiometers for each signal, the brightness of each color can be adjusted. When in shutdown, the current consumed from the battery is typically less than 1.2µA.
