In the first part of this series on switched capacitor bandgap references, Low Power Switched Cap Bandgap, the basic operation of an implementation using this ...

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 ...

Today's engineer is faced with several options when selecting capacitors for use in high reliability switch-mode power supply (SMPS) applications. Each type has advantages and disadvantages that are ...

Halo Microelectronics has introduced a switched capacitor charger dc-dc converter for single Li-ion or Li-po cells that can deliver up to 7A while drawing 3.5A from the supply. Called HL7139, it is ...

Noise management, induced by digital circuits on a p. c. board assembly, deserves the attention of power supply designers and those mastering digital, analog, and mixed-mode application problems ...

Here's how to reduce the effect of capacitor switching on your power system Last month's article discussed exactly what happens when electric utilities switch shunt capacitors: power system components ...

Bill Traue, CSRE, 8-VSB, AMD is principal of Bill Traue Technical Services. He acknowledges that when it comes to fixing dead switched-mode power supplies, the small wall-wart or line-lump type aren’t ...

Microprocessor-based devices require a regulated power supply unit that detects the loss of input power and continues to supply power for the length of time it takes to complete a memory backup. One ...

Recently a member of TDK-Lambda’s technical marketing team experienced first-hand just how much influence small diameter electrolytic capacitors can have on long-term power supply reliability.

On paper, electricity behaves in easy-to-understand, predictable ways. That’s mostly because the wires on the page have zero resistance and the switching times are actually zero, whereas in real life ...
