概览
The NCS29001 is an integrated LED driver used in LCD display backlighting applications. A configurable bill of materials allows the designer to create a highly efficient solution for a variety of LCD screen sizes.

The integrated soft start function provides excellent control during the power up sequence to avoid current overshoot. The device protects against output overvoltage, open and short LED, and thermal overload. The NCS29001 is offered in the cost effective SOIC14 package.
