LM2753  
SNVS353F FEBRUARY 2005REVISED SEPTEMBER 2016  
LM2753 High-Power Switched-Capacitor Voltage Converter and Flash LED Driver  
1 Features  
3 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  
1
Input Voltage Range: 3 V to 5.5 V  
Regulated 5-V Output  
250-mA Output Current With a 3.6-V Input  
range of 3 V to 5.5 V. The switched output, IOUT  
,
400-mA Pulsed Output Current  
(up to 500-ms Duration)  
takes less than 10 ns 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. This device uses  
only three small, low-cost ceramic capacitors.  
60-µA (Typical) Quiescent Current  
Pulse-Frequency Modulation (PFM) Regulation  
Inductor-Less Solution: Requires Only Three  
Small Capacitors  
< 1-µA Typical Shutdown Current  
The LM2753 device uses pulse frequency modulation  
(PFM) regulation. Typical operating frequency is  
725 kHz. Under no-load conditions, the LM2753  
operates on only 60 µA. If the output is connected to  
ground, the charge pump stays in the gain of 1, which  
helps limit the input current to 300 mA (typical).
