New applications for ultracapacitors offer greater energy density

New applications for ultracapacitors offer greater energy density
Devices called ultracapacitors have recently become attractive forms of energy storage: They recharge in seconds, have very long lifespans, work with close to 100% efficiency, and are much lighter and less volatile than batteries. But they suffer from low energy-storage capacity and other drawbacks, meaning they mostly serve as backup power sources for things like electric cars, renewable energy technologies, and consumer devices.

Supply monitor integrated 300µΩ sense resistor

Supply monitor integrated 300µΩ sense resistor
The LTC2947 power and energy monitor for 0 to 15VDC supply rails has been introduced by Linear Technology. Most power and energy monitoring ICs use an external sense resistor to measure current. However, choosing a sense resistor is not an easy task, especially when dealing with high currents, where available sense resistors can dissipate too much power, occupy a lot of board space or have a large impact on measurement accuracy.

DC/DC converters provide 9W from a SIP-8 package

DC/DC converters provide 9W from a SIP-8 package
Powersolve has just introduced what its says is the world’s first SIP-8 packaged DC/DC converter series to provide an isolated and regulated output voltage with up to 9W of output power. Models in the Tracopower TMR9 series are available with 2:1 (TMR 9) or 4:1 (TMR 9WI) input ranges and cover nominal inputs of 12, 24 and 48VDC. Single and dual output voltages of 3.3 to 24VDC are available within the range.

Compact supplies enable flexible use of limited space

Compact supplies enable flexible use of limited space
The trend in next-gen systems is towards miniaturisation. With a height of only 30 mm, the new LRS-35, LRS-50, LRS-75, LRS-100 and LRS-150F series from Mean Well enable system designers to use limited space flexibly. In addition, a no-load power consumption of <0.2 W to <0.5 W allows systems to easily achieve low power consumption, thus meeting energy conservation requirements.
