DescripTion  
TheLTC®3115-1isahighvoltagemonolithicsynchronous  
buck-boostDC/DCconverter.Itswide2.7Vto40Vinputand  
output voltage ranges make it well suited to a wide variety  
of automotive and industrial applications. A proprietary  
low noise switching algorithm optimizes efficiency with  
input voltages that are above, below or even equal to the  
output voltage and ensures seamless transitions between  
operational modes.
