ASYNCHRONOUS SWITCH MODE SUPPLY

摘要

There is disclosed an asynchronous switch mode power supply comprising: a subtractor for subtracting an output of the switch mode power supply from a reference signal; a filter for filtering the subtracted output; a quantiser for generating a plurality of quantiser outputs in dependence on the integrated subtracted output; and a power switch stage for connecting one of a plurality of supply voltages to the output of the switch mode power supply in dependence on the quantiser outputs.
