Supercapacitors Enhance LDO Efficiency- Part 1: Low Noise ..., combining a switcher and an LDO makes more sense in electronic systems where the DC rail voltages are less than 3.3 V and a combination of many different low voltages are within the same system. Charge pumps or switched capacitor converters use a set of capacitors rather than an inductor or transformer for energy storage and conversion.

Transformer - Wikipedia transformer is a passive electrical device that transfers electrical energy from one electrical circuit to another, or multiple circuits.A varying current in any one coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force across any other coils wound around the same core. . Electrical energy can be transferred between ...
