NCS29001 LED Backlight Driver 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 ef ficient solution for a variety of LCD screen sizes.

The NCS29001 uses a boost type converter to deliver constant current in a string of LEDs.

High accuracy PWM dimming is supported for a frequency up to 500 Hz .

The integrated soft start function provides excellent control during the power up sequence to a
