Analog-to-digital conversion module adapted for irregular sampling sequences

A controller comprising:

• a first module configured to generate a plurality of sampling trigger signals based on a first sampling sequence for a first cycle period, the first sampling sequence comprising a plurality of samples, wherein each sampling trigger signal of the plurality of sampling trigger signals is configurable to either be automatically generated or generated at a respective sampling time within the first cycle period based on the first sampling sequence;
• and
• an analog-to-digital conversion module configured to convert an analog signal into a corresponding digital value in response to the plurality of sampling trigger signals resulting in the plurality of samples.

A method for regulating a signal level at a regulated output, the method comprising:

• regulating the signal level by providing a pulse-width modulated signal to a switching circuit;
• and
• sampling by an analog-to-digital conversion module the signal level at a plurality of sampling times, wherein the analog-to-digital conversion module converts the signal level to a corresponding digital value at each sampling time of the plurality of sampling times resulting in a plurality of samples for a first modulation cycle, wherein at least some sampling times of the plurality of sampling times are nonperiodic with respect to the other sampling times of the plurality of sampling times.
