摘要：According to one embodiment, a power supply circuit includes: a first capacitorconfigured to accumulate an electric charge corresponding to an input voltage; an n-number of second capacitors configured to be connected in parallel to the first capacitor,
n being an integer equal to or larger than 1); an n-number of switches configured to berespectively connected in series to the n-number of second capacitors; a DC-DC
converter configured to step down the input voltage; and a control circuit configured toperform control to sequentially turn on the switches each time the input voltage reachesa first threshold voltage.
