General Description
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 maximum current to a Flash LED.
Flash LED current is set via a ballast resistor.
Continuous illumination current (Torch Mode) is programmed by connecting a resistor between IOUT and VOUT.
