  • Patent number: 10491099
    Abstract: A switching regulator control circuit is used in a switching regulator that converts an input voltage into an output voltage by the switching of a switching device, and generates a switching signal for controlling the ON/OFF operation of the switching device. The switching regulator control circuit has a fault detector and a fault protector. The fault detector detects, based on the duty ratio of the switching signal or a variable correlated to it and included in a control signal used to generate the switching signal, a fault state where the duty ratio falls outside the normal modulation range. The fault protector stops the switching of the switching device when the fault detector detects a fault state.

A first contact of the fuse is soldered at the circuit board at a first solder joint and a second contact is soldered at the circuit board at a second solder joint. During assembly of the circuit board at the housing, an engaging tab of the thermal fuse engages the housing whereby the housing urges the engaging tab and the first contact of the thermal fuse in a direction away from a surface of the circuit board. When the control device is assembled and in use, and when a temperature exceeds a threshold temperature so that the first solder joint at the first contact sufficiently melts, the first contact moves away from the circuit board to break the electrical connection at the first solder joint.
