LM2753 Description
The LM2753 is capable of driving a flash LED with a pulsed current of 400 mA at an input voltage of 3.6 V. A switched-capacitor doubler, the LM2753 provides a regulated 5-V output (VOUT) over an input supply range of 3 V to 5.5 V. The switched output, IOUT, takes less than 10 ns to turn on and provide maximum current to a flash LED.
