ABSTRACT:
The invention provides polyphase synchronous switching regulator circuits that include N power stages connected in parallel, with each stage synchronized to a timing control signal that is 360.degree./N out of phase from one another. Each power stage supplies current I.sub.OUT /N to the load. Current-mode and voltage-mode control implementations are described that provide efficient, low voltage, high current synchronous switching regulator circuits that have low input ripple current, low EMI, high slew-rate capability and low output ripple.
