A power supply arrangement is specified in which a capacitor with a low internal resistance, in particular a supercap (3), is connected via a means for charging (4) to an input (1) and via a load current regulator (9) to a connecting means (7) for an electrical load (8). Together with a feedback path, a control loop is formed for the load current through the electrical load (8). It is therefore possible to allow flash operation in applications such as mobile telephones with rechargeable batteries with a high internal resistance, with provision for high energy utilization from the capacitor, with controlled discharging with a regulated current. |
