Abstract
Quasi-Constant On-Time Controller. At least one example embodiment is a method of operating a power converter, comprising: charging an inductor of a switching power converter, each charging has an on-time; and then discharging the inductor while providing current to the load; and repeating the charging and the discharging at a switching frequency. During the repeating, the example method may comprise: adjusting the switching frequency proportional to a voltage difference between an output voltage and a setpoint voltage; generating an on-time reference proportional to a frequency difference between the switching frequency and a setpoint frequency, the on-time of each charging of the inductor is based on the on-time reference; and modifying the on-time proportional to the voltage difference.
