An apparatus for charging a plurality of series connected battery cells includes first and second input terminals for providing a charging voltage to the plurality of series connected battery cells. A transformer includes a primary side associated with the...

A multiphase synthetic ripple voltage generator for a multiphase DC-DC regulator including a master clock circuit that generates a master clock signal, sequence logic and a ripple regulator for each phase. The DC-DC regulator includes multiple switching ci...

A multiphase ripple voltage regulator generator employs a hysteretic comparator referenced to upper and lower voltage thresholds. The hysteretic comparator monitors a master ripple voltage waveform developed across a capacitor supplied with a current propo...
