A system comprises a pulse width modulator, a voltage sensing circuit, a pulse generator, and a sampling circuit. The pulse width modulator generates a control signal to control a switch connected to an input voltage via a primary winding and to regulate an output voltage across a secondary winding that is supplied to a load through a component connected in series with the secondary winding. The voltage sensing circuit senses a first voltage across the primary winding that represents the output voltage. The pulse generator generates a single pulse at a sampling time during a first cycle of the control signal, which is determined based on the input voltage, a voltage drop across the switch, an on-time of the switch, and the first voltage sensed during the first cycle. The sampling circuit samples the first voltage based on the single pulse at the sampling time during the first cycle.
