LTC3865/LTC3865-1  
Dual, 2-Phase Synchronous  
DC/DC Controller with  
Pin Selectable Outputs  
DescripTion  
The LTC®3865/LTC3865-1 are high performance dual  
synchronous step-down DC/DC switching regulator  
controllers that drive all N-channel synchronous power  
MOSFET stages. A constant frequency current mode  
architecture allows a phase-lockable frequency of up to  
770kHz. Power loss and noise are minimized by operating  
the two controller output stages out of phase.  
OPTI-LOOP® compensation allows the transient response  
to be optimized over a wide range of output capacitance  
and ESR values. Independent track/soft-start pins for  
each controller ramp the output voltage during start-up.  
Current foldback limits MOSFET heat dissipation during  
short-circuit conditions. The MODE/PLLIN pin selects  
among Burst Mode® operation, pulse-skipping mode,  
and continuous inductor current mode. The output volt-  
ages can be precisely programmed by pin strapping or  
external resistors.
