Using GaN for dual battery management in MHEVs
In combating climate change, electrification within the automotive sector is continuing apace. However, this is not without its challenges. John Grabowski, EV/HEV Systems Applications Manager, ON Semiconductor, explains the role of MHEVs.
TMBS rectifiers boost power density and efficiency
The surface-mount TMBS Trench MOS Barrier Schottky rectifier series at Vishay Intertechnology has been expanded with 16 new 2A and 3A devices in the eSMP series low profile SMP (DO-220AA) package. The Vishay General Semiconductor rectifiers feature a wide range of reverse voltages from 45V to 200V, while their 3A rating is the industry's highest for the SMP package to increase power density.
Power application control helps cut BoM costs
Mouser Electronics and Qorvo have introduced into the distribution channel the PAC5556 Power Application Controller. Delivering intelligent power control with extreme power density in a compact footprint, the PAC5556 mixed-signal system-on-chip (SoC) offers designers enhanced performance, reliability and energy efficiency, while helping to reduce bill of materials costs by as much as 35%.
DC/DC converters have ultra-wide input range for railway
Flex Power Modules announces the PKM7500W and PKM7100W, two new series of quarter-brick modules for powering railway rolling stock equipment. The 50W PKM7500W offers an extremely wide input voltage range of 12V to 160V, while the 100W PKM7100W has an input range of 14V to 160V.
Robust gate drivers for fast switching SiC power modules
CISSOID has delivered robust Gate Drivers for XM3 SiC MOSFET Power Modules from Wolfspeed. Aimed at high power density converters, the new Gate Driver board safely drives the fast switching SiC power modules to achieve low losses and operates in high temperature environments found inside space-constrained motor drives, compact power supplies or fast battery chargers.
Fully integrated power management IC saves board space
With features including four DC/DC buck converters, a boost DC/DC converter, and six low-dropout regulators (LDOs), the STMicroelectronicsSTPMIC1power-management IC (PMIC) satisfies the complex power demands of highly integrated application-processor based systems.
Helping engineers design faster with new digital models
RECOM Power has launched digital models for its entire product catalogue in collaboration with SnapEDA, the biggest platform for electronic component discovery & design-in. Symbols & footprints for RECOM’s entire catalogue are now available for free download via the RECOM and SnapEDA websites, helping engineers design electronics faster.
The top technology trends in power for 2020
For the past several decades, the subject of ‘power’ has been consistently viewed as a challenge focused primarily on the incremental improvement - be that by technology, by government regulations, or by shifting consumer behaviour. Much attention has been paid to how the energy we use is generated, and rightly so. Energy production is one of the world’s largest sources of carbon emissions.
Audio ADC enables far-field voice capture at four times the distance
Texas Instruments has introduced a new audio analog-to-digital converter (ADC) capable of capturing clear audio up to four times farther away than competing devices. The TLV320ADC5140 is the industry’s smallest quad-channel audio ADC with this level of performance.
Comparison of vibration energy harvesting devices
Battery replacement in portable electronics is laborious, so the search is on for more efficient power sources. Among the different energy sources under research, vibration sources seem to be the most suitable for small-scale power generation for low-power electronics. Harvesting energy by converting waste vibration energy into electrical energy is useful in replacing the finite-lifespan batteries used in monitoring sensors and wireless electroni...
