Inductors for 2-5MHz dc-dc conversion

Coilcraft had introduced screened inductors intended to reduce losses in power converters running from 2 to 5MHz, and above, at high ripple current. “The use of high switching frequencies or high ripple current allows a corresponding lower inductance value, which results in a physically smaller part for the same electrical specs,” said the firm. “XEL50xx ...

How the UK could shine in augmented reality glasses

When unobtrusive augmented-reality glasses finally make it into production, intellectual property from UK companies could be doing the heavy lifting. Some perspective Despite the hype behind some famous virtual-reality goggle brands, the problems they have solved are as nothing to those augmented-reality firms are up against. By their enclosed nature, the optics within VR goggles ...

Arm adds secure to Cortex-M for smart meters

Arm has added physical security to a Cortex-Mx processor to create a new core, the Cortex-M35P. Protection is included against invasive attacks (based on chip de-packaging), and non-invasive attacks like power and electromagnetic side-channel monitoring. The aim is to bring “smartcard levels of security to emerging applications such as smart metering, door locks and automotive”, said ...
