At PCIM in Nuremberg this week, Texas Instruments announced an automotive-qualified LLC controller for light electric vehicle charging, and demonstrated it in a three-stage ac-dc battery charger for electric two-wheelers. (LLC is an inductor-inductor-capacitor topology, see diagram) “But despite the benefits that the LLC topology can offer, including minimal standby power and low audible noise, electric vehicle manufacturers have been ...

Rhopoint Components is stocking precision current sensing resistors from VPG Foil Resistors. The 1W surface-mount RBF series measures 6.3 x 3.2mm and offers resistances between 0.01Ω and 1Ω. Tolerances down to 0.5% are available between 0.1 and 1Ω, or down to 1% from 10mΩ to 100mΩ. All the series are available with a temperature coefficient of ±25ppm/°C between -25 and ...

EPC aims to displace silicon mosfets from secondary-side synchronous rectifiers with its latest 40V GaN power transistor, designed specifically for 48V to 12V LLC dc-dc converters. “With the EPC2366, and upcoming lower voltage parts, we are expanding the GaN beach-head across low-voltage applications that have long been dominated by silicon,” said EPC CEO Alex Lidow. Packaged in 3.3 x 2.6mm ...

Danisense, the current sense transducer specialist, is introducing its ‘Online Calibration Portal’ to offer brand agnostic calibration services for current transducers. Via the new personal online portal, which will be available in Mid-May 2025 on Danisense’s website www.danisense.com, customers can book their brand agnostic calibrations for current transducers to be performed in the ISO 17025 accredited Calibration Lab from Danisense, ...

Vishay has released a digital ambient light sensor in a 4.38 x 1.45 x 0.6mm package, with AEC-Q100 qualification for automotive use. VEML4031X00, as it will be known, has a visible light spectral sensitivity designed to match the human eye, and also includes an ambient infra-red sensor for light source differentiation. “With an ambient light range from 0 to 172 ...

Abaco Systems has introduced a SOSA-aligned Open VPX 3U video graphics and GPGPU card. Powered by an Ada Lovelace architecture Nvidia RTX 5000 GPU, with 16Gbyte of GDDR6 ECC memory, GRA117S is designed to support AI and deep learning. 9,728 Cuda cores, 76 RT cores, and 304 Tensor cores are implemented, and there is support for AV1, H.265 and H.264 ...

Exhibiting a low mated height of 4.35mm, the Si-Fly LP (low profile) cable-to-board assemblies have been released by Samtec for use in data centre, HPC and AI applications. Typically in these areas the z-axis height near the IC package is limited. In addition to side-to-side and front-to-back mounting, the assemblies allow belly-to-belly PCB mounting (connectors and cages on both sides ...

At PCIM in Nuremberg today, Power Integrations revealed five 800V automotive power supply reference designs for its 1,700V InnoSwitch3-AQ flyback dc-dc converter IC: RDK-994Q – 35W 40 to 1kVdc input, 24V output, low-profile traction inverter gate-drive or emergency PSU RDK-1039Q – 18W planar transformer traction inverter gate driver or emergency PSU (pictured) RDK-1054Q – 120W planar transformer PSU to eliminate ...

Menlo Microsystems is demonstrating a way to scale its MEMS relays – micro electromechanical relays – to “power distribution and control systems to 10MW and beyond” today at PICM in Nuremberg. Based on the company’s MM9200 300V 10A single-pole single-throw switch, the demonstration is of technology behind a 1,000V and 10,000A circuit breaker being designed for the US Navy. According ...

Infineon has launched its CoolSiC MOSFET 750 V G2 technology, designed to deliver improved system efficiency and increased power density in automotive and industrial power conversion applications. The technology offers a granular portfolio with typical R DS(on) values up to 60 mΩ at 25°C, making it suitable for a wide range of applications, including on-board chargers (OBCs), DC-DC converters, auxiliaries ...
