MCP1252 Charge Pump Backlight Demo Board (MCP1252DM-BKLT)

The MCP1252 Charge Pump Backlight LED Demo Board 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 the MCP1252-ADJ. Dimming is accomplished by pulse-width modulating the shutdown 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. The PICmicro also accepts a push-button input that allows the user to adjust the white LEDs to five different light intensities, in addition to placing the system in a standby mode that consumes less than 1 uA of current (typical).

Возможности

    • Programmed MCP1252 Charge Pump control (via the PIC10F206)
    • Four white LEDs
    • PIC10F206 microcontroller:

  • Enables the MCP1252 Charge pump
  • Controls light intensity
  • Places system into sleep mode (< 1 uA)
    • Push-button interface for multiple control options
    • Baseline Flash Microcontroller Programmer (BFMP) Header for reprogramming the PIC10F206
    • 3 AAA Battery Pack (Batteries not included)
