microLED displays closer to commercialisation
As reported in Yole Développement (Yole) ‘microLED Displays 2018 report’, microLED Display technologies are improving rapidly. The report underlines the progresses made over the 18 month period preceding its release, nevertheless, many challenges remain. Last month, a variety of companies presented new microLED displays prototypes at Las Vegas CES.
Microcontroller balancing act demands a new process
A new semiconductor process combines lower leakage with low standby current modes, writes Graeme Clark, Renesas Electronics Europe
GaN power transistor claims to be highest current-rated
GaN transistors from GaN Systems now extend to 120A, 650V. The GaN E-HEMT increases the power density of 20 to 500 kW power conversion systems, including automotive traction inverters, very high power on-board chargers (OBC), large-scale energy storage systems, and industrial motor drives.
Solutions to speed time to market for AI acceleration chip
It has been announced by Mentor, a Siemens business, that artificial intelligence (AI) semiconductor innovator Graphcore successfully met its silicon test requirements and achieved rapid test bring-up on its Colossus Intelligence Processing Unit (IPU) by using Mentor’s Tessent product family.
Super-junction MOSFETs offer high efficiency
MDmesh M6 series super-junction transistors from STMicroelectronics (ST) are in stock at Mouser Electronics. Designed for high efficiency in medium-power resonant and hard-switching converter topologies, the MOSFETs enable increased power density in equipment such as battery chargers, power adapters, PC power supplies, LED drivers, telecom and server power supplies, and solar micro-inverters.
Low power consumption 150mA voltage regulators
A new series of voltage regulators has been launched by Torex Semiconductor, with the XD6216 series. The XD6216 series are positive voltage regulator ICs with 28V of operation voltage. The series consists of a voltage reference, an error amplifier, a current limiter, a thermal shutdown circuit and a phase compensation circuit plus a driver transistor.
GaN HEMTs feature new topologies and current modulation
The CoolGaN gallium nitride (GaN) HEMTs from Infineon Technologies are in stock at Mouser Electronics. Featuring high efficiency and power density, the CoolGaN high-electron-mobility transistors (HEMTs) facilitate high-speed switching in semiconductor power supplies.
AEC-qualified FETs exploit GaN technology for autonomous vehicles
The EPC2206, and EPC2212 eGaN FETs by Efficient Power Conversion (EPC) are both discrete transistors in wafer level chip-scale packaging (WLCS) with 80 and 100V DS ratings respectively. They have received AEC Q101-qualification and will be joined by more discrete transistors and ICs designed for the harsh automotive environment, says the company.
Advantages of load switches over discrete MOSFETs
In this video, Alek Kaknevicius, Applications Engineer at Texas Instruments, discusses TI’s integrated load switches and what advantages they bring over a discrete MOSFET solution. In general, load switches are put in between a power supply and a load. When the load needs to be on, the load switch is closed. And when the load can be turned off, the load switch is opened.
Use a low-quiescent-current switcher for high-voltage conversion
Texas Instruments explains that, in battery-operated environments, it’s important to pay attention to quiescent current when designing your power system block diagram. Some applications, such as cordless handheld garden tools, lighting controls and cordless lawnmowers, have low-quiescent-current specifications. These tools operate with a battery pack that has an operating voltage range from 12 to 48V or higher.
