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 ...

The continuous evolution of microelectronics tends to underestimate the importance of passive components. Actually, capacitors, resistors, and inductors play a fundamental role in all electronic ...

A power supply’s output capacitors - which are typically ceramic capacitors with values between 100nF and 100μF - cost money, take up space, and, in the case of delivery bottlenecks, can be difficult ...

What are output capacitors and how do they impact power supplies? Simulating a circuit to reduce the amount of capacitors in a supply. What is adaptive voltage positioning? A power supply’s output ...

Power Integrations is aiming at larger home appliances needing to meet IEC60335 with an X-capacitor discharger that can empty 6µF in under a second. X-capacitors are part of the EMC input filter of ...

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.

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 ...

I was inspecting the fans in my tower, trying to track down the source of an unusual humming noise, when I noticed something strange in my power supply.<BR><BR>The fan was spinning as usual, but past ...

We've continue to cover a number issues with iMac G5s apparently overheating, and generating excessive fan noise in an apparent effort to cope with the heat. In some cases, the overheating can cause ...
