DC1022A, Demonstration Board using LTC3210-1 low noise charge pump for four main LEDs

DC1022A, Demonstration Board using LTC3210-1 a low noise charge pump designed to drive four MAIN LEDs and one high current CAM LED. The LTC3210-1 requires only four small ceramic capacitors plus two resistors to form a complete LED power supply and current controller. The maximum display currents are set with a 30.1K ohm resistor for the Main display and a 24.3K ohm resistor for the CAM display. Current for each LED is controlled with a precision internal current source
