3-phase 600 kHz buck controller

14 August 2002 Power Electronics / Power Management

Linear Technology's LTC3732 is a 3-phase, 5-bit VID, 600 kHz, synchronous step-down switching regulator that drives 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 600 kHz per phase to minimise the RMS current dissipated by the ESR of both the input and output filter capacitors. Uses true current mode architecture to provide output currents up to 60 A while maintaining current balancing between the three output power stages to within ±5%. For efficiencies at light loads the LTC3732 switches between output stage shedding and Burst Mode operation. With integrated 5-bit VID DAC, output voltages of 1,075 V to 1,85 V are programmable in 25 mV increments. A differential amplifier provides true remote sensing of both the high and low side of the output voltage. Housed in low profile 36-pin SSOP package.
