com LM2754 800mA Switch ed Capacitor Flash LED Driver with Time -Out Protection September 2006 LM2754 800mA Switched Capacitor Flash LED Dri ver with Time-Out Protection General De scription The LM2754 is an integrated l ow noise, high current switched capacit or DC/DC converter with four regulated current sinks.
The device is optimized for driving 1 to 4 high power white LED s in parallel with a maximum current of 800mA.
Maximum efficiency is achieved over the input voltage range by activel y selecting the proper gain based on th e LED forward voltage and current requi rements.
