摘要： A power supply control circuit detects a reference voltage VD corresponding to an intermediate voltage of a Hi Side FET and a Lo Side FET, when a short-circuit fault of the Lo Side FET is generated, and compares a threshold value VIN−VrefH and the reference voltage VD using a comparator COMP. The power supply control circuit determines that the short-circuit fault is generated, when the reference voltage VD is less than the threshold value VIN−VrefH and a switching control signal (HiDr) is in an ON state. Likewise, the power supply control circuit detects the reference voltage VD of the Hi Side FET and the Lo Side FET, when a short-circuit fault of the Hi Side FET is generated, and compares a threshold value VrefL and the reference voltage VD using the comparator COMP. The power supply control circuit determines that the short-circuit fault is generated, when the reference voltage VD is more than the threshold value VrefL and a switching control signal (LoDr) is in an ON state.

Each of the power supply units includes a transformer; a stopped state latch part configured to latch a control signal for controlling outputting of the power supply unit in a predetermined stopped state to stop the outputting, after passage of a first time in response to detection of an overcurrent on a primary side of the transformer; and an outputting restriction part configured to set the control signal in a predetermined restricted state to restrict the outputting of the power supply unit without stopping the outputting, after passage of a second time in response to detection of an overcurrent on a secondary side of the transformer. The second time is shorter than the first time.
