摘要： A main body of an electronic part has multiple electrodes, to which multiple terminals are connected. The terminals include a normal terminal and a fuse terminal, each of which extends from lands formed in a printed board so as to hold the main body at a position above and separated from a board surface of the printed board. The fuse terminal has a cut-off portion having a smaller width than other portions of the fuse terminal, so that the cut-off portion is melted down when excess current flows in the fuse terminal. The normal terminal holds the main body at the position above and separated from the board surface even in a case of melt-down of the cut-off portion.

摘要： A main body of an electronic part has multiple electrodes, to which multiple terminals are respectively connected. The terminals include a fuse terminal and a normal terminal, each of which extends from the main body to a printed board so that the main body is supported at a position above and separated from a board surface of the printed board. The fuse terminal has an intermediate portion between an electrode-connected portion and a land-connected portion. The intermediate portion has a cut-off portion having a smaller width than other portions of the fuse terminal, so that the cut-off portion is melted down when excess current flows in the fuse terminal. The intermediate portion extends in a direction parallel to the board surface or in a direction inclined to the board surface at an angle smaller than 90 degrees.

摘要： A switching power supply converts an input voltage to a predetermined output voltage by controlling a switching device. The switching power supply includes a controller and a current detector. The controller controls the switching device. The current detector detects electric current flowing through the switching device. The controller starts a forced-OFF action to forcedly turn OFF the switching device when the current detected by the current detector exceeds a predetermined threshold and then ends the forced-OFF action at a start of a predetermined switching period.

摘要： A printed board includes an insulated base, a wiring pattern, and an inspection interrupting portion. The wiring pattern is disposed on a first surface of the insulated base, and includes a wiring portion, a land, and an interrupting portion disposed between the wiring portion and the land. The inspection interrupting portion is made of a same material with the interrupting portion and has a same pattern with the interrupting portion. In order to assure an interrupting performance of the interrupting portion, the inspection interrupting portion is inspected instead of the interrupting portion by applying an inspection current to the inspection interrupting portion.

摘要： A power supply device comprises: a first linear regulator, which receives a voltage from a direct-current power supply at all times and outputs a first voltage; a step-down switching regulator, which receives the voltage from the direct-current power supply through a path via a power supply switch and outputs an intermediate voltage, and a second linear regulator, which receives the intermediate voltage and outputs a second voltage. The power supply device outputs a higher one of the first voltage and the second voltage. The first linear regulator has a smaller current consumption and a higher minimum operating voltage than the second linear regulator. When the voltage supplied from the direct-current power supply is lower than or equal to a predetermined threshold value, the switching regulator drives a main switching component interposed in series with a voltage input-output path to turn on at all times. The second linear regulator executes an output operation of the second voltage during a full-on period, during which the main switching component is driven to turn on at all times.

摘要： A switching power supply device includes a switching circuit and a control circuit. The switching circuit includes multiple switching elements, an inductor, and a capacitor. The control circuit compares an input voltage of the switching circuit with a predetermined threshold voltage set for an operation switch, and controls the switching circuit to perform the operation switch between at least two power control operations based on a comparison result. The at least two power control operations includes at least two of a buck operation, a buck-boost operation, or a boost operation. The control circuit further performs an inrush current restriction operation in response to the operation switch in order to restrict a flowing of an inrush current to one of the switching elements, which turns on and outputs the input voltage through the inductor in response to the operation switch.

摘要： An electronic control device includes a turn-on restriction section capable of performing a restriction operation to restrict a turn-on speed of a switching element. The turn-on restriction section includes a comparator. The comparator receives a voltage of a main terminal of the switching element connected to a smoothing circuit and determines whether the voltage of the main terminal of the switching element reaches a threshold voltage. The turn-on restriction section performs the restriction operation for a predetermined time from a start of a turn-on period in which the switching element is turned on. The turn-on restriction section stops the restriction operation after the predetermined time has elapsed. The predetermined time is set to a time from the start of the turn-on period until the voltage of the main terminal of the switching element reaches the threshold voltage.
