FEATURES  
DESCRIPTIO  
■
Up to 80% Efficiency  
TheLT®1932isafixedfrequencystep-upDC/DCconverter  
designed to operate as a constant-current source. Be-  
cause it directly regulates output current, the LT1932 is  
ideal for driving light emitting diodes (LEDs) whose light  
intensity is proportional to the current passing through  
them, not the voltage across their terminals.  
■
Inherently Matched LED Current  
■
Adjustable Control of LED Current  
■
Drives Five White LEDs from 2V  
■
Drives Six White LEDs from 2.7V  
■
Drives Eight White LEDs from 3V  
■
Disconnects LEDs In Shutdown  
With an input voltage range of 1V to 10V, the device works  
from a variety of input sources. The LT1932 accurately  
regulates LED current even when the input voltage is  
higher than the LED voltage, greatly simplifying battery-  
powered designs. A single external resistor sets LED  
current between 5mA and 40mA, which can then be easily  
adjusted using either a DC voltage or a pulse width  
modulated (PWM) signal. When the LT1932 is placed in  
shutdown, the LEDs are disconnected from the output,  
ensuring a quiescent current of under 1µA for the entire  
circuit. The device’s 1.2MHz switching frequency permits  
theuseoftiny, lowprofilechipinductorsandcapacitorsto  
minimize footprint and cost in space-conscious portable  
applications.
