Abstract
A circuit for an operating device includes a first clocked converter as a power factor corrector and a buck post-regulator, which has a SELV barrier or galvanic isolation barrier extending through the power factor corrector. The power factor corrector has a control circuit concentrated on the input side, which is provided for supplying power from a conventional AC power supply network, and data thereof is to be transmitted, via two optocouplers, for a complete logic link between the input and output side. The output side is configured to connect to a DC load, in particular an LED or a series circuit of multiple LEDs, provided for general lighting technology. Both optocouplers can be operated digitally, e.g., in a pulsed manner, to compensate for their non-linearity, temperature drift, aging and noise.
