Boost power supplies are popular for creating higher dc voltages from low-voltage inputs. As the power demands from these supplies increase, however, a single power stage may be insufficient. This ...

Linear Technology Corporation introduces the LTC3128, a high efficiency, input current-limited buck-boost supercapacitor charger with active charge balancing for 1 or 2 series supercapacitors. The ...

The age of creative thinking in dc/dc converters is not over. So-called “new” topologies may appear periodically, but if they are not resonant types, almost invariably they are just variations of the ...

Lightweight, small-size, and high-power-density power converter systems, which use only switches and capacitors in their power stage, have no need for transformers or inductors in their design. This ...
