FEATURES  
DESCRIPTIO  
TheLTC®3727LX-1isahighperformancedualstep-down  
switching regulator controller that drives all N-channel  
synchronouspowerMOSFETstages.Aconstant-frequency  
currentmodearchitectureallowsphase-lockablefrequency  
of up to 550kHz. Power loss and noise due to the ESR of  
the input capacitors are minimized by operating the two  
controller output stages out of phase.
