The LTC3731CG#TRPBF from Analog Devices is a PolyPhase synchronous step-down switching regulator controller designed for high current DC/DC power supplies. It drives N-channel external power MOSFETs in a phase-lockable fixed frequency architecture, operating at frequencies up to 600kHz per phase. This 3-phase controller offers 120° phase separation, effectively tripling the fundamental frequency to improve transient response and minimize RMS current losses in filter capacitors.
Key features include a wide operating voltage range of 3.8V to 7V and an adjustable frequency from 225kHz to 680kHz. The controller supports PWM, Stage Shedding, or Burst Mode operation for optimized light load efficiency. It incorporates OPTI-LOOP compensation to minimize output capacitance and provides adjustable soft-start current ramping. Protection features include a defeatable timed short-circuit shutdown and current foldback.
This device is available in a 36-SSOP package, suitable for surface mounting. The operating temperature range is 0°C to 70°C (TA). Applications include desktop computers, servers, and high-performance notebook computers requiring high output current DC/DC power solutions.
