Buck-boost converters are a form of switching-mode power supply that can supply a regulated DC output from a source voltage either above or below the desired output voltage. This can be particularly ...

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 ...

Linear Technology’s LTC3119 is an efficient, monolithic buck-boost converter that operates with inputs from 2.5 to 18 V (Fig. 1), making it well-suited to operate from one- to four-cell Li-ion ...

If you need to regulate your power input down to a reasonable voltage for a project, you reach for a switching regulator, or failing that, an inefficient linear regulator. What if you need to boost ...

The LDS8720 is a matrix LED driver featuring high efficiency boost converter operating at an input voltage range from 2.7 to 5.5 V. It does not require an external Schottky diode, and offers ...

Several bias voltages are needed for supplying and operating an LCD panel. In most cases, specialised integrated circuits with several charge-pumps are used to generate the different voltages. As the ...
