Biased Backlighting
The MCP1252-ADJ 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. The device
allows the input voltage to be lower or higher than the output
voltage, by automatically switching between buck/boost
operation.
Today’s new color displays require a pure white light for
backlighting. White light emitting diodes have become the
component of choice. The MCP1252-ADJ is an excellent
choice for biasing the backlighting. 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
shutdown pin of the device.
