MULTIPHASE DC TO DC CONVERTER

摘要

A multiphase DC to DC converter (100) includes an input (Vin), an output (Vout), at least first and second converters (104, 106), an inductor (L), an output capacitor (C), and a drive circuit The drive circuit is configured for switching the first and second converters (104, 106) with a predetermined phase shift therebetween The output capacitor (C) is operatively coupled between the first and secon converters (104, 106) and the output (Vout) The inductor (L) can be placed either at the input side or the output side When placed at the input side, the inductor (L) is operatively coupled between an input capacitor and the first and second converters When placed at the output side, the inductor is operatively coupled between the first and second converters and the output capacitor (C) The multiphase DC to DC converter is capable of achieving lossless switching transitions and negligible ripple current in the output capacitor (C)
