Abstract: The present invention provides an isolated regulating power converter with opto-coupled feedback of output (Vo) with respect to a reference level (Vset) for regulation to a converter controller. The sense of the feedback signal is such that the opto-coupler LED is ON when Vo<Vset and OFF when Vo>Vset with the effect that the LED current and power loss is zero during the times when Vo>Vset, as is normal case for many controllers at low or no load. This saves power under such circumstances. Additionally, as the LED does not load the output during this time, the proportion of time for which Vo>Vset is increased, meaning that the timing at which the switch must again be on to meet demand is extended, producing a further power saving.
