    摘要： The present invention discloses a power supply circuit for driving an LED lamp and a power supply method. The power supply circuit is constituted by an AC-DC converter by adopting DCM-DCM. Also, the power supply circuit adopts a valley fill circuit to reduce rippling of output current and adopts the DCM-DCM to stabilize a link voltage, thereby realizing a power factor correction circuit having two-stage structures. Thus, an input voltage of the flyback converter may be improved, and a high reverse voltage may be applied.

    摘要： Disclosed are a system and a battery management integration circuit using an incremental analog-to-digital converter (ADC), which can reduce the consumption of the amount of a bias current. The system includes an incremental ADC configured to perform accumulation on an analog signal during an oversampling period and a bias current generator configured to provide a bias current for the accumulation of the incremental ADC. The bias current generator provides a first amount of the bias current in a first period defined from start timing of oversampling to preset timing during the oversampling period, and provides a second amount of the bias current, smaller than the first amount of the bias current, in a second period subsequent to the first period.
