FeaTures  
DescripTion  
The LT®3470 is a micropower step-down DC/DC con-  
verter that integrates a 300mA power switch, catch diode  
and boost diode into low profile 3mm × 2mm DD and  
ThinSOT™ packages. The LT3470 combines Burst Mode  
and continuous operation to allow the use of tiny induc-  
tor and capacitors while providing a low ripple output to  
loads of up to 200mA.

Hysteretic Mode Control  
With its wide input range of 4V to 40V, the LT3470 can  
regulateawidevarietyofpowersources,from2-cellLi-Ion  
batteries to unregulated wall transformers and lead-acid  
batteries. Quiescent current in regulation is just 26µA in  
a typical application while a zero current shutdown mode  
disconnects the load from the input source, simplifying  
power management in battery-powered systems. Fast  
currentlimitingandhystereticcontrolprotectstheLT3470  
and external components against shorted outputs, even  
at 40V input.
