Reka bentuk rujukan oleh: Microchip Technology
MCP1252DM-BKLT, Demo Board for the MCP1252 Charge Pump Backlight demonstrates the use of a Charge Pump device in an LED application. The board also serves as a platform to evaluate the MCP1252 device in general. The MCP1252-ADJ is an excellent choice for biasing the back lighting or driving other LED applications. Light intensity is controlled uniformly through the use of ballast resistors. The peak intensity is set by the feedback to the MCP1252-ADJ. Dimming is accomplished by pulse-width modulating the shut-down pin of the device. The board also feature a PIC10F206 microcontroller in a SOT23 package, which is used to provide an enable signal to the MCP1252
