Single-pin high voltage connectors for up to 100kV DC
GES High Voltage a company in high voltage connectivity, has significantly improved and optimised its Series 100 single-pin high voltage connectors designed for operating voltages up to 100kV DC. The plugs and receptacles are fully compatible with the previous version, the redesign is available since February 2018.
Voltage regulator provides big performance in tiny footprint
The STLQ020 low-dropout (LDO) voltage regulator from STMicroelectronics relieves the familiar trade-offs between quiescent current, output power, dynamic response, and package size, to give designers extra freedom.
Low-power MCUs extend battery life for wearables
Designers of IoT sensors, environmental sensors, smartwatches, medical/preventive health wearables, and other size-constrained devices can now increase battery life and functionality using the ultra-low power MAX32660 and MAX32652 microcontrollers from Maxim Integrated Products. These microcontrollers (MCUs) are based on the Arm Cortex-M4 with FPU processor and provide designers the means to develop advanced applications under restrictive power c...
USB PD chipset adopted by Hosiden for smartphone adapters
Dialog Semiconductor plc has announced it is shipping in high volume its USB PD chipset to Hosiden Corporation, a Japanese manufacturer of charger adapters for mobile devices. The chipset is used in Hosiden’s CBC2153 model USB PD-compliant adapter, designed for one of Japan’s leading mobile TELCO providers. With Dialog’s market share of more than 60% in AC/DC rapid charging integrated circuits for smartphone adapters.
Eliminating EMI effects in high performance DAQ systems
This video from Texas Instruments covers the TIDA-01054, a multi-rail power reference design for eliminating EMI effects in high performance DAQ systems.
Energy efficiency in direct current systems
The introduction of a host of activities for energy efficiency improvement has come from the increase of the trend towards efficient utilisation of limited resources. For DC systems especially, monitoring their performance and error-free operation is fundamental. Photovoltaic and battery storage systems are particularly relevant here and the focus is also evidently on the power supplies of emerging electromobility solutions.
New power models expanded to 8kW in 1U
Magna-Power Electronics has increased the power capability of its popular 1U (1.75” high) SL Series to 8 kW with the addition of 17 new models. The new 8kW models further extend the SL Series lead for the most programmable power in 1U within its product class. The SL Series now spans 99 models from 1.5-8kW, from 5Vdc to 1000Vdc, and from 1.5Adc to 250Adc.
The efficient redundancy for power supplies
Maximilian Hülsebusch from PULS here reviews advances in reliable power system availability in the event of a short circuit. N+1 redundant power module connection guarantees reliable system availability even if a power supply fails. However, the common use of decoupling diodes in such modules causes a large voltage drop leading to high power losses generating heat.
TVS diode arrays protect I/O and power ports from ESD
Littelfuse, Inc. has introduced two series of AEC-Q101-qualified, unidirectional TVS Diode Arrays optimised to protect I/O and power ports against electrostatic discharges (ESDs). SP1053 and SP1054 Series TVS Diode Arrays (SPA Diodes) integrate avalanche breakdown diodes fabricated using proprietary silicon avalanche technology to protect each pin.
Tantalum capacitors for non-critical medical devices
AVX Corporation has released the T4Z Medical Series HRC4000 medical-grade tantalum capacitors. Designed to replace commercial capacitors in the filtering, hold-up, and charging circuits of non-critical medical devices that require high-reliability and strict change control.
