The evolution of smart MOSFET technologies
A review of MOSFET advances helps predict where the technology is likely to head. Ashita Mirchandani, Bastian Lang • Infineon Technologies The past 50 years have seen unprecedented changes enabled by technology. The trend will continue with emerging technologies such as e-mobility, the Internet of Things (IoT), artificial intelligence, connectivity and 5G. At the heart […]
How to keep transients from disrupting low-power circuits
It can be challenging to give a highly dynamic load a stable voltage when the power supply sits several feet away from the device under test. Bill Griffith • Keysight Technologies Today’s integrated circuits put a highly dynamic load on their power supply. This behavior poses a challenge during testing when IC power comes from […]
Advanced current sensing for next-gen electronics
Contactless current sensing provides the fast response that state-of-the-art power circuits depend on. Michael DiGangi • ACEINNA The next generation of electronic products will be more powerful and flexible than ever. The advanced circuitry to drive them needs intelligent power management to realize the desired performance. Application spaces like robotics and micro-electromechanical systems (MEMS) rely […]
SOIC-16-sized dc-dc converters provide 3 kVdc/1 min isolation
New dc/dc converters in a SOIC-16 package feature 5-V (4.5-5.5 V) inputs and a semi-regulated 5-V output are rated at either 0.5 W (R05C05TE05S) or 1 W (R05CTE05S). Line and load regulation figures are specified across the full temperature range, and there is no minimum load requirement, making the parts ideal for applications that have […]
100-W railway/industrial dc-dc converter sports 12:1 input range
TRACO POWER announces the new TEP 100UIR family of 100 Watt DC/DC converters in a fully encapsulated, compact Quarter brick footprint with an ultra-wide 12:1 input range for harsh environments in railway and industrial applications. The ultra-wide 12:1 input voltage range (9-75 / 14-160 VDC) lets system builders reduce design variations required to satisfy varying […]
Compact 300/120-W GaN ac adapters meet DoE efficiency specs
CUI Inc announced the expansion of two GaN desktop ac-dc power supply series to its SDI product family, broadening their product range for the GaN adapter line. The SDI300G-U and SDI300G-UR offer 300 W of continuous power from a compact desktop package and boast up to 100% increase in power density compared to non-GaN units. […]
Identifying the right medical power supply
Special considerations apply for power supplies when even small electrical currents pose a shock hazard. Dermot Flynn, Chris Jones • Advanced Energy The consequences of leakage current came to the forefront in the 1970s, and since then technical standards for the safety and effectiveness of medical electrical equipment have evolved to become the most stringent […]
High-current ac harmonic filter capacitors offer built-in fail-safe protection
Cornell Dubilier announces its new, patented, PCD series of high current, AC harmonic filter capacitors offering dual, built-in, fail-safe protection systems, one at each end of the capacitor. Similar capacitors in this category have one open-circuit pressure device located under the top cover that requires the capacitor to be mounted from its bottom stud. With […]
