Abstract:
1. A DC/DC converter comprising: an input to which an input current (Iin) is supplied, an output at which an output current (Iout) is provided, and a current control circuit coupled to the input and the output, comprising: wherein the unit that provides an instantaneous value signal (Sin) comprises a measuring device that measures the input current (Iin) of the DC/DC converter or an input voltage (Vin) proportional to the input current (Iin) of the DC/DC converter, wherein the current control circuit further comprises a first and a second low-pass filter and a comparison device, the first low pass filter is coupled between the unit that provides the instantaneous value signal (Sin) and a first input of the comparison device and provides an average value of the instantaneous value signal (Sin) as an averaged instantaneous value signal ( the second low pass filter is coupled between the internal input and a second input of the comparison device and provides the average of the pulsed reference signal (Sref′) as an averaged pulsed reference signal ( the comparison device comprises an internal output that provides a control signal (Sctrl) dependent on a comparison of the averaged instantaneous value signal ( wherein the control signal (Sctrl) adjusts the output current (Iout) of the DC/DC converter.
