High power switched capacitor voltage convertor/flash led driver.

LM2753, High Power Switched Capacitor Voltage Convertor/Flash LED Driver

The LM2753 is capable of driving a Flash LED with a pulsed current of 400mA at an input voltage of 3.6V.

A switched capacitor doubler, the LM2753 provides a regulated 5V output (VOUT) over an input supply range of 3.0V to 5.5V.

The switched output, IOUT, takes less than 10ns to turn on and provide m
