INTRODUCTION
FEATURES
Chapter 2. Installation and Operation
The MCP1252 Charge Pump Backlight LED Demo Board uses the MCP1252-ADJ to
power four white LEDs. A PIC10F206 microcontroller in a SOT23 package is used to
provide an enable signal to the MCP1252. It 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 µA of current (typ.).
The PIC10F206 microcontroller is programmable, allowing the user to modify or
develop their own firmware routines to further evaluate the MCP1252 in this
application.
The MCP1252 Charge Pump Backlight LED Demo Board has the following features:
• Programmed MCP1252 charge pump control (via the PIC10F206)
• Four white LEDs
• PIC10F206 microcontroller
• Push button interface for multiple control options
• Baseline Flash Microcontroller Programmer (BFMP) Header for reprogramming
• 3 AAA battery pack (batteries not included)
the PIC10F206
- Enables the MCP1252 charge pump
- Controls light intensity
- Places system into Sleep mode (< 1 µA)
