Abstract
A circuit assembly for operating a load may include an input for inputting an input voltage and/or current. The circuit assembly may further include an output for outputting an output voltage and/or current. The circuit assembly may further include an at least partially digital switching regulator with a feedback loop. A loop gain of the feedback loop may be frequency-dependent where the frequency ranges from 3 Hz to 20 Hz.
Claims10
A circuit assembly for operating a load, comprising:
- an input for inputting an input voltage and/or current;
- an output for outputting an output voltage and/or current;
- and
- a switching regulator with a feedback loop,
- wherein the feedback loop includes:
- a micro-controller;
- and
- an integrator having a frequency-dependent gain;
- wherein a loop gain of the feedback loop is frequency-dependent;
- and
- wherein the loop gain of the feedback loop in the frequency range below 100 Hz is greater than the loop gain in the frequency range above 100 Hz;
- wherein the integrator comprises an operational amplifier directly connected to a resistor and a capacitor;
- and
- wherein a second feedback loop is formed between the operational amplifier and the capacitor.
