.. LM2754 800mA Switched Capacitor Flash LED Driver with Time-Out Protection September 2006 LM2754 800mA Switched Capacitor Flash LED Driver with Time-Out Protection General Description The LM2754 is an integrated low noise, high current switched capacitor DC/DC converter with four regulated current sinks. The device is optimized for driving 1 to 4 high power white LEDs in parallel with a maximum current of 800mA. Maximum efficiency is achieved over the input voltage range by actively selecting the proper gain based on the LED forward voltage and current requirements. Two external low power resistors set the desired current for Torch and Flash modes. The TX pin allows...
