LTC1735

The LTC1735 is the newest member of Linear Technology’s third generation of synchronous step-down controllers. This controller uses the same constant frequency, current mode architecture and Burst Mode operation as the industry standard LTC1435 and LTC1437 controllers but with improved features. With OPTI-LOOP compensation, new protection circuitry, tighter load regulation and stronger MOSFET drivers, the LTC1735 is ideal for the current and future generations of mobile CPUs. A companion part, the LTC1736, has all the features of the LTC1735 ...
