Typical Power IC Type : Step Down Regulator (Normal, LDO, Ultra Low Dropout)1.Vin always greater than Vout2.Less of external components, smaller board size3.Low cost, but High thermal & Low efficiency Step Down? Buck Converter(Async. & Sync.)1.Vin always greater than Vout2.More of external components, bigger board size3.High cost, but Low thermal & High efficiency Step Up? Boost Converter(Async. & Sync.)1.Vin always smaller than Vout2.More of external components, bigger board size3.High cost, but Low thermal & High efficiency Step Up? Charge pumpConverter1.Vin always smaller than Vout2.Less of external components, smaller board size3.Low cost, but smaller Iout & bigger Vout ripple
