FEATURES  
DESCRIPTIO  
PolyPhaseTM Valley Current Mode Controller  
TheLTC®3709isasingleoutput,dualphase,synchronous  
step-down switching regulator. The controller uses a  
constant on-time, valley current control architecture to  
deliver very low duty cycles without requiring a sense  
resistor. Operating frequency is selected by an external  
resistor and is compensated for variations in input supply  
voltage.Aninternalphase-lockedloopallowstheLTC3709  
to be synchronized to an external clock.  
Synchronizable to an External Clock with PLL  
Coincident or Ratiometric Tracking  
Sense Resistor Optional  
2% to 90% Duty Cycle at 200kHz

High Efficiency at Both Light and Heavy Loads  
Power Good Output Voltage Monitor

Adjustable Current Limit  
A TRACK pin is provided for tracking or sequencing the  
output voltage among several LTC3709 chips or an  
LTC3709 and other DC/DC regulators. Soft-start is ac-
