150V synchronous step-down DC/DC includes surge protection
https://www.electronics-lab.com/150v-synchronous-step-dcdc-includes-surge-protection/
Linear Technology designed the LTC3895 to be a non-isolated DC/DC controller with a high input voltage capability that can eliminate the need for surge suppression and operate continuously with a high input voltage. The synchronous step-down switching regulator controller drives an all N-channel MOSFET power stage. Its 4V to 140V (150V abs. Max.) input voltage […]
Microchip’s first ARM processor with cryptographic engine
https://www.electronics-lab.com/microchips-first-arm-processor-with-cryptographic-engine/
Clemens Valens @ elektormagazine.com discuss about the new CEC1302 microcontroller from Microchip. This is the first Microchip microcontroller with an ARM core. He writes: Based on a Cortex-M4 core its main feature is its integrated cryptographic engine supporting public key encryption, symmetric key encryption, secure hashing and random number generating. Besides its ARM core the […]
Windows 95 on an Apple Watch
https://www.electronics-lab.com/windows-95-on-an-apple-watch/
Nick Lee managed to install Windows 95 on an Apple Watch. The process was not straightforward but he succeed after a few tweaks to the WatchKit app. The Apple Watch take about an hour to boot Windows 95 due to the reason that it’s an emulated version and not a virtualized one. Apple Watch runs […]
