INTRODUCTION
Today’s new color displays require a pure white light for backlighting. White
light-emmitting diodes have become the component of choice. The MCP1252-ADJ is
an excellent choice for biasing the backlighting or driving other LED applications. Light
intensity is controlled uniformly through the use of ballast resistors. The peak intensity
is set by the feedback (FB) to the the MCP1252-ADJ. Dimming is accomplished by
pulse-width modulating the shutdown pin of the device.
