On the drawing boards: Next-gen IoT power control electronics may sit on a PCB smaller than a U.S. quarter
Here’s the rub when it comes to modernizing the outlets, switches and circuit breakers that characterize ac electrical systems: Any innovations must interoperate with an installed base of equipment that may have been in place for decades. Manufacturers say issues surrounding compatibility with installed equipment have slowed the rate of introduction for technologies such as […]
Four-terminal shunt resistor provides low-resistance, high-accuracy current sensing
Stackpole’s CSSK3637 is a four-terminal shunt that provides very low resistance values which have been expanded to 0.5 to 6 milliohms, in tolerances as low as 0.5% and TCR of 50 ppm. In addition, this all-metal shunt has an operating temperature up to 170C, providing excellent stability for a wide range of end products. The […]
Miniaturized open frame power supplies optimized for medical and industrial apps
Murata announced the expansion of its PQ line which is comprised of open frame AC/DC converters. The PQU1000 series was designed for industrial and medical applications requiring a high level of safety. The line meets IEC62368-1 and EN60601-1 third edition standards for industrial and healthcare applications. Given that, it is suitable for Body Floating (BF) […]
DC/DC converter ICs feature fast load transient response
ROHM Semiconductor introduced a new power supply technology, QuiCur, that improves the load transient response characteristics (response performance involving response speed, and voltage stability of subsequent stage) of DC/DC converter ICs (switching regulators) and LDOs (linear regulators). In recent years, the continuing electrification of applications in all areas has increased the number of electronic components, […]
DC-DC converter output tracks input
Flex Power Modules has expanded its BMR491 range of digital, quarter-brick DC/DC converters with 2 new variants. Power ratings now available are 1400 W continuous / 2400 W peak (BMR4912307/856), and 1540 W continuous / 2450 W peak (BMR4913208/857). The new variants all feature the Flex Power Modules’ ‘Hybrid Regulated Ratio (HRR)’ technique where output […]
Efficient step-down dc-dc converter module delivers 72 W
Murata announced the development of the MYC0409, the industry’s highest power density (5.4kW/inch3), 48 Vin divide-by-4 charge pump capacitor divider module with all passive components integrated into a low profile PSiP package. Capable of delivering up to 72 watts of power with a peak efficiency of around 97-percent, the interleaved, switching capacitor architecture is based […]
STMicroelectronics’ 50W GaN converter enables high-efficiency power designs in consumer and industrial applications
The STMicroelectronics VIPerGaN50 simplifies building single-switch flyback converters up to 50 Watts and integrates a 650V gallium-nitride (GaN) power transistor for superior energy efficiency and miniaturization. With its single-switch topology and high integration, including current-sensing and protection circuitry also built-in, the VIPerGaN50 comes in a compact and low-cost 5mm x 6mm package. The speed of the integrated […]
Ultra-high efficiency, low component count AC/DC supplies include power factor correction
Eggtronic has expanded its EcoVoltas family of high-efficiency AC/DC architectures with the launch of SmartEgg, a Zero Voltage Switching (ZVS) solution for power applications in the 75 to 1kW range that need both output voltage regulation and power factor correction (PFC). By enabling much higher no-load-to-full-load efficiency and a 50% smaller bill of materials (BOM) […]
