Abstract
A DC-DC converter system (1, 1′) according to the invention is provided with an input (In) for feeding in an input voltage (U_in), a step-up controller section (2) for increasing the input voltage (U_in) in a controlled manner to a controlled first output voltage (U_out1) and for providing the first output voltage (U_out1) at a first supply output (Out1), and a voltage conversion section (3) for converting the input voltage (U_in) into a second output voltage (U_out2) in a manner controlled by a control device of the step-up controller section (2) and for providing the second output voltage (U_out2) at a second supply output (Out2). The DC-DC converter system (1) according to the invention having two supply outputs (Out1, Out2) is based on an expansion of a step-up controller with a SEPIC circuit, wherein the DC-DC converter system comprises only a single control device (S1) and a switching device (T1) which can be controlled by the control device.
