LT3500  
Monolithic 2A Step-Down  
Regulator Plus Linear  
Regulator/Controller  
FEATURES  
DESCRIPTION  
The LT®3500 is a current mode PWM step-down DC/DC  
converterwithaninternal2.3Aswitch.Thewideinputrange  
of 3V to 40V makes the LT3500 suitable for regulating  
power from a wide variety of sources, including automo-  
tive batteries, 24V industrial supplies and unregulated  
wall adapters.  
n
Wide Input Range: 3V to 36V Operating,  
40V Maximum  
n
Short-Circuit Protected Over Full Input Range  
n
2A Output Current Capability  
n
Adjustable/Synchronizable Fixed Frequency  
Operation from 250kHz to 2.2MHz  
n
Soft-Start/Tracking Capability  
Resistor-programmable 250kHz to 2.2MHz frequency  
range and synchronization capability enable optimization  
between efficiency and external component size. Cycle-  
by-cycle current limit, frequency foldback and thermal  
shutdown provide protection against a shorted output.  
The soft-start feature controls the ramp rate of the output  
voltage, eliminating input current surge during start-up,  
and also provides output tracking.  
n
Output Adjustable Down to 0.8V  
n
Adjustable Linear Regulator/Driver with 13mA  
Output Capability  
n
Power Good Comparator with Complimentary  
Outputs  
Low Shutdown Current: 12μA

n
Thermally Enhanced 3mm × 3mm DFN or 16-Pin  
MSOP Package  
The LT3500 contains an internal NPN transistor with feed-  
back control which can be configured as a linear regulator  
or as a linear regulator controller.
