Abstract
A power source circuit capable of improving an efficiency of using energy of a chemical battery cell by responding suitably to an intermittent change in a load current, by during a load burst period in an odd-numbered order, a load is driven by power accumulated in a first power storing section and, during a load burst period in an even-numbered order, a load is driven by power accumulated in a second power storing section. The chemical battery cell does not discharge during the load burst period. Therefore, an amount of a voltage having dropped due to an internal impedance of a power supplying section becomes small and, as a result, when the power source circuit is applied to the electronic device which becomes inoperable due to a temporary voltage drop in the power source, an operational life of the power supplying section is made longer.
