<p>In one embodiment a power conversion arrangement comprises a switching converter (DC) with an input which is supplied with an input voltage (Vin) and a first output (Out1) to provide a first output voltage (Vout1) as a function of the input voltage (Vin), a linear regulator (LDO1) with an input coupled to the first output (Out1) of the switching converter (DC), the linear regulator (LDO1) having a second output (Out2) to provide a second output voltage (Vout2) as a function of the first output voltage (Vout1) to a connectable electrical load (CS), means for sensing (MSI) a load current (Iload) at the second output (Out2) of the linear regulator (LDO1), the means being connected to the second output (Out2) of the linear regulator (LDO1), and means for influencing (MVA) the first output voltage (Vout1) as a function of the load current (Iload), the means (MVA) being connected to the first output (Out1) of the switching converter (DC) and to the means for sensing (MSI) the load current (Iload). Furthermore, a power management circuit and a method for power conversion are described.</p> |
