A low cost, high efficiency 30A low profile PolyPhase converter is described.
The growing need for very high current logic supplies often exceeds the capability of a single buck (step-down) converter. The solution is a PolyPhase converter where two or more buck sections work in parallel to deliver a single high current output.
The LTC1629 is a current mode, PolyPhase controller that interleaves the clock signals of two synchronous buck stages, reducing input and output ripple currents without increasing the switching frequency. Because of the output ripple current cancellation, ...
