1. An adaptive DC-DC boost converter arrangement comprising
a circuit board with a plurality of electronic components mounted thereon,
the plurality of electronic components comprising:
an adaptive DC-DC boost converter circuit and a boost decoupling capacitor connected to an output of the adaptive DC-DC boost converter circuit, the adaptive DC-DC boost converter circuit comprising:
a DC-DC boost converter having a converter set value input, a boost supply input, and a boost voltage output;
an adaptive DC-DC boost control unit having a control input and a control output; and
an acoustical noise suppression filter having a filter input connected to the control output of the adaptive DC-DC boost control unit and a filter output connected to the converter set value input of the DC-DC boost converter,
wherein the boost decoupling capacitor is a ceramic capacitor, and the acoustical noise suppression filter is configured to filter out resonance frequencies of the circuit board caused by varying voltages applied to the boost decoupling capacitor mounted on the circuit board, and the acoustical noise suppression filter has a pass bandwidth of less than 4 kHz.
