ABSTRACT:
A semi-clockless, cascaded, current-mode regulator has a first regulator that receives a clock signal from a controller. By ‘semi-clockless’ is meant that a clock signal is applied to the first of a cascaded plurality of regulators, and that as a result of the cascading of clock delay circuits in each of the regulators, the remaining regulators receive sequentially delayed versions of the clock signal applied to the first regulator. The regulators are coupled to control the operations of associated pulse width modulation controlled switching circuits. Outputs of the switching circuits are combined to realize a multi-phase output voltage.
