The LTC1629CG#TRPBF from LT 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 RMS ripple currents in input and output capacitors.
Key electrical specifications include a wide input voltage range from 4V to 36V and a very low dropout operation with a 99% maximum duty cycle. The controller offers a phase-lockable fixed frequency between 150kHz and 300kHz, with an effective switching frequency of 1.8MHz. It also provides -1% output voltage accuracy and true remote sensing capabilities.
This controller is suitable for high current applications and systems requiring 15A to 200A of output current, with the ability to expand up to twelve evenly phased controllers. The multiple phase technique improves transient response and simplifies thermal design. The LTC1629CG#TRPBF is available in a 28-lead SSOP package, suitable for surface mounting.
Applications include desktop computers, internet servers, large memory arrays, and DC power distribution systems. The design incorporates features like adjustable soft-start current ramping, internal current foldback, and an optional timed short-circuit shutdown.
