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 efficient 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
avoid current overshoot. The device protects against output
overvoltage, open / short LED, and thermal overload. The NCS29001
is offered in the cost effective SOICâ14 package.
