DescripTion  
n
Dual, 180° Phased Controllers Reduce Required  
The LTC®3869 is a high performance dual synchronous  
step-down switching regulator controller that drives all  
N-channelsynchronouspowerMOSFETstages.Aconstant  
frequency current mode architecture allows a phase-  
lockable frequency of up to 780kHz. Power loss and noise  
due to the ESR of the input capacitors 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. A wide 4V to 38V input supply range  
encompasses most battery chemistries. Independent TK/  
SS 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, or continuous inductor current mode and allows  
the IC to be synchronized to an external clock.
