Microchip Boost RGB LED Driver Demo Board Boost Controller for MCP1643 for RGB LED Driver

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.

Powered by one-cell Alkaline, NiCD, or NiMH battery or by external power supply
Start-up voltage: 0.8V at full load
MCP1643 PWM switching frequency: 1 MHz
RGB multiplexing frequency: 70 Hz
Fixed output current for all colors: 350 mA
