Input Voltage Range: 3.0V to 5.5V  
Regulated 5V Output  
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 out-  
put (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 be-  
tween IOUT and VOUT. This device uses only three small,  
low-cost ceramic capacitors.  
250mA Output Current with a 3.6V input  
400mA Pulsed Output Current (up to 500ms duration)  
60µA (typ.) Quiescent Current  
PFM Regulation  
Inductor-less solution: requires only 3 small capacitors

1µA Typical Shutdown Current  
10-pin LLP Package (No Pullback):  
3mm x 3mm x 0.75mm  
LM2753 uses Pulse Frequency Modulation (PFM) regula-  
tion. Typical operating frequency is 725kHz. Under no-load  
conditions, LM2753 operates on only 60µA. If the output is  
connected to ground, the charge pump stays in the gain of 1  
which helps limit the input current to 300mA (typ.)
