LED Boost Controller Demonstration Board

The MCP1650 3W White LED Demo Board demonstrates Microchip’s MCP165X Boost Controller product family in a battery powered white LED application. The MCP1651 (8-pin MSOP) with low battery detect is featured in a SEPIC converter topology with an input voltage range of 2.0V to 4.5V.

Features


• MCP1651 in a SEPIC application configured in Bootstrap mode. This application circuit regulates the output to 3.6V while delivering 700mA of current as the input voltage varies from 2.0V to 4.5V
• Dimming and flashing modes are provided by a PIC10F206 microcontroller
• Program connector allows access to the PIC10F206 program code via Microchip’s ICD 2 In-Circuit Debugger
