Dual Output Boost – LED Driver / LCD Bias
P RODUCTION D ATASHEET
DESCRIPTION The LX1744 is a compact high efficiency step-up boost
regulator for driving white or color LEDs in LCD lighting applications while supplying the necessary LCD bias voltage with an additional integrated boost converter.
Designed for maximum efficiency and featuring a psuedo-hysteretic PFM topology (that decreases output voltage ripple), the LX1744 minimizes system cost and condenses layout area making it ideal for PDA, smart-phone, and digital camera applications.
While the LCD Bias generation is implemented using an internal N-Channel MOSFET, the LED ...
