Power converter enables SMPS with 5V output voltage
STMicroelectronics has introduced a high-voltage power converter that allows designers to build an ultra-low-consumption, simple and cost-effective SMPS with a 5V output voltage.The converter is tailored to provide the auxiliary supply to MCUs in IoT devices that are permanently connected to the internet or a local network.
DC converters meet high levels of energy efficiency
Claimed to offer significant operating improvements to reduce energy consumption for today’s electronics systems, the R3 series of DC converters from Mornsun, are available from distributor PowerPax.
Automotive grade inductor operates up to +180°C
Vishay Intertechnology has introduced an automotive grade IHLP low-profile, high-current inductor in the 5050 case size featuring a +180°C continuous operating temperature rating for under-the-hood applications. The IHLP-5050FD-8A provides a wide range of inductance values from 0.22 to 22µH in a low 6.4mm profile package.
Digital-to-analogue data converter awarded certification from DLA
The latest 12-bit space grade Digital-to-Analogue data Converter (DAC) from e2v has been awarded QML class V certification from the US Defense Logistics Agency (DLA).e2v’s EV12DS130B DAC device family has been awarded the globally recognised space qualification of QML class V by the US DLA, increasing e2v’s portfolio of QML qualified data converters.
12 & 20V MOSFETs offered in dual asymmetric package
Vishay Intertechnology has announced what it claims to be the industry's first AEC-Q101-qualified 12 and 20V MOSFETs in a dual asymmetric power package. To save space and power in high-efficiency synchronous buck converters for automotive applications, the SQJ202EP and SQJ200EP n-channel TrenchFET devices each combine a high- and low-side MOSFET in the compact 5x6mm PowerPAK SO-8L dual asymmetric package.
Industrial DC/DC converters power non-flight-critical programs
Industrial level DC/DC converters and EMI filters are available in models ranging from 5 to 100 watts, from VPT. Converters in the VHR series are reliable to power non-flight-critical programs in military, avionics, and unmanned systems as well as manufacturing equipment and controls.
GaN FET driver is claimed to be the world's fastest
Peregrine Semiconductor has announced what it claims to be the word’s fastest GaN FET driver, the UltraCMOS PE29100. Designed to drive the gates of a high-side and a low-side GaN FET in a switching configuration, the PE29100 delivers the industry’s fastest switching speeds, shortest propagation delays and lowest rise and fall times to AC/DC converters, DC/DC converters, class D audio amplifiers and wireless charging applications.
Optimising automotive pre-boost power supplies
In the first part of a three part feature, Matthias Ulmann of Texas Instruments describes the problem involved in designing and optimising an automotive pre-boost power supply, shows the impact of a cold start test pulse on such a supply, and discusses a typical pre-booster specification.
SoC optimisation to the next level
Minimising the PCB footprint and the BoM cost implies embedding the Power Regulation Network (PRNet) in the SoC. Meanwhile, minimising drastically the SoC power consumption involves implementing several modes of activity to turn on and off different functions of the SoC, which generates noise on the supply lines during mode switching.
MOSFETs offer reduced package sizes & increased reliability
An extension on the offer of higher voltages has been announced by Vishay Intertechnology, of the600V and 650V E Series power MOSFETswith three new n-channel devices in the compact PowerPAK SO-8L package.
