The LTC
®
1629/LTC1629-PG are multiple phase, dual,
synchronous step-down current mode switching regula-
tor controllers that drive N-channel external power MOSFET
stages in a phase-lockable fixed frequency architecture.
The PolyPhase
TM
controller drives its two output stages
out of phase at frequencies up to 300kHz to minimize the
RMS ripple currents in both input and output capacitors.
The output clock signal allows expansion for up to 12
evenly phased controllers for systems requiring 15A to
200A of output current. The multiple phase technique
effectively multiplies the fundamental frequency by the
number of channels used, improving transient response
while operating each channel at an optimum frequency for
efficiency. Thermal design is also simplified.
