GETTING STARTED
The MCP1252 Charge Pump Backlight LED Demo Board comes fully assembled and
tested. The board requires 3 AAA batteries as a power source for the application.
2.3.1
Insert three AAA batteries into the battery pack on the bottom of the board. As soon as
the system powers up, the internal program of the PIC10F206 will initialize and remain
in a low-power sleep mode (<1 µA) until the S1 button is pressed by the user.
The MCP1252 Charge Pump Backlight LED Demo Board does not need a power
switch or power jumper because of the “standby” or “sleep” mode of the PIC10F206
microcontroller. Upon entering Sleep mode, the system requires less than 1 µA (typ) of
current. So, with three AAA batteries used in the application (at 1250 mAh per battery),
the system’s power requirements in Sleep mode are minimal (the “shelf life” of an alka-
line battery is 5-7 years, whereas the system current load in Sleep mode would
discharge the battery pack in about 400 years!).
