DC/DC Switching Regulators: Introduction
Nisshinbo Micro Devices provides various DC/DC switching regulators that cover Buck, Boost, inverting, flyback and Buck-Boost topologies. We offer a wide operating voltage range from low operating voltage type that design for energy-harvest to 80V maximum rating products. As well as we have a wide coverage of output current, also Controller type with external MOSFET are available. Furthermore, depending on application demand, several variation can be offer such as switching modes, noise immunity, inductor built-in module and so on.
