Abstract: A voltage converter performs a step-up operation and step-down operation in parallel. The step-up operation raises an input voltage to a voltage that is N (N?1) times the input voltage. The step-down operation lowers the input voltage to a voltage that is M (0?M?1) times the input voltage. The voltage converter outputs the voltage transformed through the step-up operation and the step-down operation from output terminals. A current detection circuit detects an output current. A step-up adjustment circuit decreases N if the output current is higher than a reference current, and increases N if the output current is lower than the reference current. A step-down adjustment circuit decreases M if the output current is higher than a reference current, and increases M if the output current is lower than the reference current. The reference current is higher than the reference current.

Abstract: A wire with terminal includes a wire in which a core is covered with a coating, and a terminal 20 including a wire barrel 24 to be crimped to the core exposed from the coating of the wire and an insulation barrel 26 to be crimped to the coating of the wire. The wire is pulled rearwardly from the terminal. Recesses 26B are provided on a surface of the insulation barrel 26 to be crimped and openings of the recesses 26B are shaped to become narrower toward a rear side. As the wire is pulled more rearwardly, the coating penetrating into the recesses 26B moves rearwardly of the recesses 26B to be compressed and hardened and becomes less likely to come out of the recesses 26B. Thus, impact strength can be enhanced.
