DESCRIPTIO  
FEATURES  
TheLT®3681isanadjustablefrequency(300kHzto2.8MHz)  
monolithic buck switching regulator that accepts input  
voltages up to 34V (36V maximum). A high efficiency  
0.18Ω switch is included on the die along with a boost  
Schottky diode and the necessary oscillator, control, and  
logic circuitry. An undedicated power Schottky diode is  
integrated into the LT3681 to minimize the solution size.  
Current mode topology is used for fast transient response  
and good loop stability. Low ripple Burst Mode operation  
maintains high efficiency at low output currents while  
keeping output ripple below 15mV in a typical application.  
In addition, the LT3681 can further enhance low output  
current efficiency by drawing bias current from the output
