2mm × 2mm DFN and MS10  
Description  
Features  
The LT®3502/LT3502A are current mode PWM step-down  
DC/DC converters with an internal 500mA power switch,  
in tiny 8-lead 2mm × 2mm DFN and 10-lead MS10  
packages.Thewideinputvoltagerangeof3Vto40Vmakes  
the LT3502/LT3502A suitable for regulating power from a  
wide variety of sources, including 24V industrial supplies  
and automotive batteries. Its high operating frequency  
allows the use of tiny, low cost inductors and capacitors,  
resulting in a very small solution. Constant frequency

making the LT3502A particularly suitable for automotive  
applications.
