Offered with fixed output voltages of 4.75 V, 5.0 V, 5.25 V and 5.5 V or an adjustable output voltage, the MIC2875 and MIC2876 2-MHz boost regulators from Micrel are capable of supplying up to 2 A of output current, while occupying just 122 mm2 of board space. These synchronous regulators also achieve efficiency of up to 95% and are well-suited for operation from a single-cell lithium battery and providing ...

Modular DC-DC switching voltage converters (or voltage regulators) are fully integrated devices that take away most of the complexity of power supply design — but not all. One of the key areas that are still left to the design engineer’s discretion is the choice of components for, and layout of, the energy storage and filtering circuits. In principle, these look like simple circuits comprising a few resisto ...
