Look no further than the BD71847AMWV power management IC, according to Rohm, which optimised it particularly for those very NXP’s i.MX 8M mini application processors Built on a BCD process, the chip can produce all power rails required by the processor as well as feed DDR and system IO. Its dc-dc converters operate at up ...

Austrian chemists have developed a red phosphor that could improve the efficacy of white LEDs, by creating a narrow peak of emission at 614nm – in the middle of the eye’s 610-620nm peak red sensitivity. The material is a particular form of Sr[Li2Al2O2N2]:Eu2+, dubbed ‘salon’ by the researchers, which “meets all the requirements for the ...

The benefits of self-driving cars are likely to prompt vehicle owners to drive more, and that extra distance could partially or completely offset the potential energy-saving benefits that automation may provide, according to a University of Michigan study. It considers the expectation that self-driving cars will yield significant improvements in safety, traffic flow and energy ...
