LX1744 Product details

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.

KEY FEATURES
◾ > 90% Maximum Efficiency
◾ Low Quiescent Supply Current
◾ Externally Programmable Peak Inductor Current Limit for Maximum Efficiency
◾ Logic Controlled Shutdown
◾ < 1µA Shutdown Current
◾ Dynamic Output LED Current and LCD Bias Voltage Adjustment via Analog Reference or Direct PWM Input
◾ 14-Pin TSSOP or 16-Pin MLPQ Package

APPLICATIONS
◾ Pagers
◾ Smart Phones
◾ PDAs
◾ Handheld Computers
◾ General LCD Bias Applications
◾ LED Driver
