Silicon IP significantly reduces power consumption of flash memories
Although requiring more computing power to run feature rich applications programmes, connected battery-based devices use the minimal energy to ensure the longest usage without recharge. As a result, fabless companies need to hunt down every ‘mA’ to satisfy the low-power expectations of their SoC users.
Bi-stable power relay designed for energy smart applications
ZETTLER electronics has unveiled the AZ 7621 P relay series. The latching power relay can switch 16AMP at 250VAC. Its electric life expectancy is 50K cycles operations at maximum ambient temperature of up to 85°C.
Medically certified power supplies offer Class I or II inputs
A series of medically certified 300W external power supplies has been announced by TDK Corporation. Certified to the latest IEC 60601-1 & 60601-1-2 medical standards, products in the DTM300 series have 4,000VAC isolation from input to output and are offered with either a Class I or Class II input.
GaN transistors enhance accuracy of power system simulations
GaN Systems has witnessed a surge in the number of customers designing and deploying power systems using their GaN transistors. Customers have recognised that GaN devices significantly improve power efficiency and power density.
Toward all-solid lithium batteries
For the first time, a team at MIT has probed the mechanical properties of a sulfide-based solid electrolyte material, to determine its mechanical performance when incorporated into batteries.
Cut data centre costs with a new power supply architecture
Modern power supply architectures can cut percentage points from data centre electricity bills, writes Bob Cantrell, senior application engineer, Ericsson Power Modules
Creating a negative output voltage using a buck converter
A theory of operation as well as schematics and performance data to enable a the quick implementation of a circuit which require a negative supply and in which only a positive supply is available in the system. By Owain Bryant, Vishay Intertechnology
DC/DC converters meets railway technology
The trend throughout the electronics industry towards ever higher packing densities has left its mark on DC/DC converters, as Recom introduces models with 20 to 120W output
Cost-effective power supply ranges suit more applications
Two power supply ranges have been announced by WAGO which provide additional functionality to suit a wider range of applications such as vending, slot and coffee machines, as well as heating controls and ventilation systems.
Power supply sequencing simplified
The challenges in designing a multiple power supply multiply with each additional supply rail, says Nathan Enger, senior applications engineer, Linear Technology
