WHAT IS THE MCP1252 CHARGE PUMP BACKLIGHT LED DEMO BOARD?
WHAT THE MCP1252 CHARGE PUMP BACKLIGHT LED DEMO BOARD KIT
INCLUDES
The MCP1252 Charge Pump Backlight LED Demo Board demonstrates the use of a
charge pump device in a LED application. The board also serves as a platform to
evaluate the MCP1252 device generally.
The MCP1252-ADJ device used in this application is an inductorless, positive-regulated
charge pump DC/DC converter. The device generates an adjustable output voltage. It
is specifically designed for applications requiring low noise and high efficiency, and is
able to deliver up to 120 mA output current. In addition, a charge pump is a low-cost,
compact and simple solution for an application, as it only requires one external capacitor
to transfer charge from the input supply to the regulated output.
The MCP1252 allows the input voltage to be lower or higher than the the output voltage
by automatically switching between buck and boost operation. This makes it especially
suited for battery applications, allowing the system voltage to be maintained even after
the batteries have discharged below the system voltage level, further extending the
overall charge life of the battery.
