  "textContent": "An in-vehicle power supply device includes an input end configured to be connected to an in-vehicle secondary battery, an output end configured to be connected to an in-vehicle load, an external signal input port configured to receive an activation signal, a first converter unit connected to the input end and the output end, and a second converter unit connected in parallel to the first converter unit. The first converter unit includes a first drive power supply configured to constantly receive power suppled from the input end, and a first voltage converter operable in response to the power received by the first drive power supply to constantly output power from the output end. The second converter unit includes a second drive power supply activated by the activation signal received by the external signal input port, a converter controller configured to start to operate in response to the activating of the second drive power supply, and a second voltage converter configured to start to operate in response to the starting of the operating of the converter controller so as to output power from the output end. The in-vehicle power supply device increases power efficiency.",
