The LTC1629CG#TRPBF from Analog Devices is a multiple phase, dual, synchronous step-down current mode switching regulator controller. It is designed to drive N-channel external power MOSFET stages in a phase-lockable fixed frequency architecture. The PolyPhase controller drives its two output stages out of phase at frequencies up to 300kHz, minimizing ripple currents in input and output capacitors.
Key features include a wide input voltage range of 4V to 36V, a maximum duty cycle of 99.5%, and a typical switching frequency of 220kHz. It supports up to 12 phases for higher current applications and offers true remote sensing for positive and negative output terminals. The controller includes RUN/SS for soft-start and optional timed short-circuit shutdown, current foldback, and OPTI-LOOP compensation for optimized transient response.
This device is available in a 28-SSOP package and is suitable for surface mount applications. Its design simplifies thermal management and improves transient response, making it ideal for high current applications.
Applications include desktop computers, internet servers, large memory arrays, and DC power distribution systems.
