Semiconductors have been enjoying an unaccustomed turn in the media spotlight since the recent shortage that forced many automakers to slow or suspend production. The latest news on the semiconductor scene is that Nexperia, an expert in the high-volume production of essential semiconductors, has acquired Newport Wafer Fab, which operates a semiconductor production facility in… Read more »
Power Integrations has expanded its InnoSwitch3-AQ family of devices, which combine a MOSFET, primary and secondary controllers and Fluxlink reinforced isolated feedback into a single IC. The new family members feature a 900 V primary MOSFET, which is designed for safe and reliable operation during system voltage transients while reducing the number and cost of… Read more »
Silicon Mobility, a provider of digital controls for EV powertrains, says its control system improves inverter and motor efficiency by 2% to 4.6% compared to the industry-standard SVPWM control technique. During the 34th International EV Symposium, Silicon Mobility and Cascadia Motion presented their latest research results, in which Optimized Pulse Pattern (OPP) modulation increased the… Read more »
Nexperia has announced new 0.55 mΩ RDS(on) 40 V power MOSFETs in the LFPAK88 package for automotive (BUK7S0R5-40H) and industrial (PSMNR55-40SSH) applications. The company says the devices are the lowest RDS(on) 40 V parts it has ever produced. They deliver higher power densities than traditional D2PAK devices and offer improved performance in both avalanche and… Read more »
Power Integrations, a maker of high-voltage integrated circuits for energy-efficient power conversion, has announced its 600 V, 12 A Qspeed diode, the AEC-Q101-qualified QH12TZ600Q. The company says the device’s Qrr of 14 nC at 25° C improves the efficiency of an onboard charger’s PFC stage and reduces the thermals of the PFC MOSFETs. Senior Product… Read more »
