LTC4020EUHF#PBF - Brand New Linear Technology IC Chips
-
Description
The LTC®3731 is a PolyPhase® synchronous step-down switching regulator controller that drives all N-channel external power MOSFET stages in a phase- lockable fixed frequency architecture. The 3-phase controller drives its output stages with 120°phase separation at frequencies of up to 600kHz per phase to minimize the RMS current losses in both the input and output filter capacitors. The 3-phase technique effectively triples the fundamental frequency, improving transient response while operating each control ler at an optimal frequency for efficiency and ease of thermal design. Light load efficiency is optimized by using a choice of output Stage Shedding or Burst Mode operation.
