Abstract
The present disclosure is directed to a switching power converter having a regulated output voltage or output current. The power converter uses a control unit having a signal conditioning circuit to produce a control voltage signal, which is used to drive a power stage of the converter. The signal conditioning circuit includes a comparator that compares a measured electrical quantity to a reference value representative of a desired regulated output quantity, and produces a digital detection signal based on the comparison. A control actuator uses the digital detection signal to produce a correction signal, which is received by an averaging circuit. The averaging circuit then produces the control voltage signal based on an average of the correction signal.
