DESCRIPTIO  
FEATURES  
The LTC®3731H is a PolyPhase® synchronous step-down  
switching regulator controller that drives all N-channel  
external power MOSFET stages in a phase-lockable fixed  
frequency architecture. The LTC3731H is rated for opera-  
tion up to 140°C junction temperature. The 3-phase con-  
troller drives its output stages with 120° phase separation  
at frequencies up to 600kHz per phase to minimize the  
RMS current losses in both the input and output filter  
capacitors. The 3-phase technique effectively triples the  
fundamentalfrequency,improvingtransientresponsewhile  
operating each controller at an optimal frequency for  
efficiencyandeaseofthermaldesign. Lightloadefficiency  
is optimized by using a choice of output Stage Shedding  
or Burst Mode operation.
