BL8040

BL8040 High Efficiency 1.2MHz 30V Boost LED Driver DESCRIPTION BL8040 is a step-up converter designed for driving up to 7 series white LED's from a single cell Lithium Ion battery. Its low 250mV feedback voltage reduces power loss and improves efficiency. Optimized operation frequency can meet the requirement of small LC filters value and low operation current with high efficiency. Internal soft start function can reduce the inrush current. Tiny package type provides the best solution for PCB space saving and total BOM cost. BL8040 is available in SOT23-6 package that is PB free. TYPICAL APPLICATION FEATURES  2.5V to 5.5V Input Voltage  Drivers up to 8 Series WLEDs  Low 250mV Feedback Voltage  1.2MHz Fixed Switching Frequency  Internal 1.6A Switch Current Limit  Internal Compensation  Thermal Shutdown  Over Voltage Protection  Dimming with wide Frequency Range  Available in SOT23-6 Package APPLICATIONS  Camera Flash White LED  PDA LED back light ...
