High-efficiency step-down switching regulators for positive voltages are very common, however negative step-down switching regulators (negative voltage in, negative voltage out, common ground) are not ...

Commonly used 3-pin linear voltage regulators, for example the LM317, cannot handle input voltages in excess of about 30V. The LR8A from Supertex Inc is a new, adjustable three pin regulator that can ...

Power-supply designers frequently encounter projects where the input voltages are much higher compared to the low output voltages usually require to power the target equipment. Typical output needs ...

This charge-pump circuit, using just a few diodes and capacitors, ups the input voltage by a factor of 1.5 in contrast to the usual voltage-doubling output. Micropower product designs sometimes ...
