LT8641 – 65V, 3.5A Synchronous Step-Down Silent Switcher
https://www.electronics-lab.com/lt8641-65v-3-5a-synchronous-step-silent-switcher/
The LT8641 is a monolithic, constant frequency, current mode synchronous (external schottky diode is not necessary) step-down switching regulator. Its 3V to 65V input voltage range makes it ideal for 12V or 24V automotive and industrial applications. It delivers up to 3.5A of continuous output current and peak loads of 5A. Output voltages can be […]

Tom from Magic Smoke writes: This is my first time designing a PCB for MSP430. I really like the NRF24L01+ booster pack but I would like something smaller to use for remote temperature sensors. With that in mind I’ve designed a 24.5 x 50 mm PCB (2 on a 5×5 cm prototype) featuring MSP430G2553 and […]
Cortex-M-based MCUs Set Pace For Automotive Design
https://www.electronics-lab.com/cortex-m-based-mcus-set-pace-automotive-design/
AUTomotive Open System Architecture (AUTOSAR) is a worldwide automotive consortium trying to create and establish an open and standardized software architecture for automotive electronic control units (ECUs). However, as is always the case with industry consortiums and standards, they are not endorsed by all interested parties, and, to complicate matters even more, not all applications […]
Sensirion solves long-standing stability problem in metal-oxide gas sensors
