Abstract
A switching regulator includes a digital feedback control circuit to regulate the output voltage. The frequency output of a voltage controlled oscillator responsive to the output voltage is periodically counted. The accumulating count is continuously compared with a reference count. The elapsed time for this count to accumulate to a value equaling the reference count determines the duty cycle of periodic conduction through the switching device of the switching regulator.
