INTRODUCTION
FEATURES
Chapter 2. Installation and Operation
The MCP1650 Multiple White LED Demo Board uses the MCP1650 IC to power the
nine white LEDs which are connected in series. A PIC10F202 microcontroller in a
SOT-23 6 pin package is used to provide the PWM signal to the MCP1650. It also
accepts a push button input that allows the user to adjust the white LED's to three
different intensities of 100%, 50% and 25%.
The PIC10F202 microcontroller is programmable, allowing the user to modify or
develop their own firmware routines to further evaluate the MCP1650 in this
application.
The MCP1650 Multiple White LED Demo Board has the following features:
• Programmed MCP1650 White LED intensity control via the PIC10F202
• Nine white LEDs connected in series
• PIC10F202 is used to generate the PWM signal which controls the intensity of the
• Push button selection for three levels of intensity control
• Includes one battery holder for three AA batteries (batteries not included)
