Abstract

This paper investigates into enriching a (step-down) classic Fibonacci switched capacitor converter voltage target ratios set by applying a multiphase switching. Simple theoretical closed-form expressions for equivalent output resistances are obtained using charge flow balance analysis that also provides a useful insight into switched capacitor and output voltage ripples. It is shown that employing a balanced multiphase switching allows for essential switched capacitor and peak-to-peak output voltage ripple (or, alternatively, output filter capacitance) reduction.
