Unusual design constraints sometimes reveal the unfriendly side of everyday components and circuits. A case in point is the design of power-supply-regulation circuitry in which the primary power ...

Voltage regulator IC’s, with 3 pins, from LM7805 and LM7812 series are excellent for usage in voltage regulator circuits. If you need higher currents, up to 3 A, you must add a complementary ...

You can generate a tiny dc supply voltage of a just a few hundred millivolts using an additional positive voltage connected to the feedback resistor of a dc-dc converter. The need for such a ...

For the PDF version of this article, click here. As nonisolated synchronous buck power converters continue pursuing higher switching frequencies, the key limiting factor has become switching losses in ...

For as versatile and inexpensive as switch-mode power supplies are at all kinds of different tasks, they’re not always the ideal choice for every DC-DC circuit. Although they can do almost any job in ...
