DESCRIPTION  
Adjustable Over-Voltage Protection Allows for  
Single or Series LED Operation  
The LM3553 is a fixed frequency, current mode step-  
up DC/DC converter with two regulated current sinks.  
The device is capable of driving loads up to 1.2A  
from a single-cell Li-Ion battery.  
Four Operating Modes: Torch, Flash, Indicator,  
and Voltage Mode (4.98V)  
Programmable Flash Pulse Safety Timer in 16  
Steps  
The LM3553 includes a TX pin that forces Torch  
mode during  
synchronization between the RF power amplifier and  
Flash/Torch modes. It also includes a multi-function  
pin (M/F) that can serve as a GPIO and a hardware  
RESET pin.  
a

TX Input Ensures Synchronization with RF  
Power Amplifier Pulse or Prevents LED from  
Overheating  
LED Disconnect During Shutdown  
Flash/Imager Synchronization via FEN Pin  
Active Low Hardware Reset  
The LM3553 is available in a 3mm by 3mm package.
