摘要
An interleaved DC-DC converter according to one or more embodiments includes a control circuit and N boost converters that are connected in parallel. The control circuit includes: an output voltage detection circuit that compares a detected voltage with a reference voltage, and outputs a comparison result as an error signal; N PWM generators that respectively generate pulses that on/off drive switching elements of the N converters; N current error amplifiers that compare current signals detected by respective current detectors with the error signal, and that outputs comparison results as feedback signals to the respective PWM generators; a differential detector that detects a difference between one feedback signal and another feedback signal for each of the feedback signals; and a latch circuit that stops all switching operations of the N converters when the differential detector detects that any one of the differences is a predetermined threshold value or more.
