Linear Technology AN77 PolyPhase Converters for High Current Applications
As logic systems require higher currents, paralleling several power regulators is often necessary. This document introduces smart PolyPhase techniques that interleave clock signals to reduce input and output ripple current without increasing switching frequency. By using the LTC1629 or LTC1628 controllers, designers can achieve high efficiency and use smaller components like inductors and capacitors.
