摘要： An adaptive DC-DC boost converter arrangement and an electronic circuit including such an arrangement are provided. The arrangement includes a circuit board with a plurality of electronic components mounted thereon, implementing an adaptive DC-DC boost converter circuit and a boost decoupling capacitor. The adaptive DC-DC boost converter circuit comprises a DC-DC boost converter having a converter set value input, a boost supply input, and a boost voltage output, and an adaptive DC-DC boost control unit having a control input and a control output. An acoustical noise suppression filter is present 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.
