Abstract
A DC/DC converter circuit includes an input capacitor (C11), an indicator (L11), a diode (D11), a transistor (T11) and a control circuit (18). The control circuit operates to control the transistor (T11). An output capacitor (C21) is connected between the output and the input of the circuit. Connection in this way usefully reduces the size of the output capacitor.
Claims10
A DC/DC converter circuit comprising:
- an input node for receiving an input DC signal;
- an output node for outputting an output DC signal;
- a first capacitor connected between the input node and ground;
- an inductor connected between the input node and an intermediate node of the circuit;
- a diode connected in forward bias between the intermediate node and the output node;
- a transistor connected between the intermediate node and ground;
- a control circuit for controlling operation of the transistor and connected thereto;
- and
- a second capacitor connected to the output node,
- characterised in that the second capacitor is connected between the output node and the input node.
A DC circuit including a battery, a load connected to the battery, and a capacitor, wherein the capacitor is connected in series with the battery and acts as a storage device for supplying the load with a voltage different to that supplied by the battery.
