• Please explain the principle of voltage step-up in a DC/DC converter.
    • Similarly to step-down, energy is accumulated in an inductor, and the voltage is converted in on/off operation; but the circuit configuration is different. When the low side switching transistor is on, energy is stored in the inductor. When it turns off, the input power supply energy and the energy stored in the inductor are supplied to the output. By repeating this operation, a higher voltage than the input voltage can be generated.
