Winner Trameto – Power management of micro energy harvesting The OptiJoule energy harvesting power management ICs (EH PMICs) are a simple, effective and economical way to address the challenge of powering wireless IoT edge devices. Battery replacement is prohibitively expensive and environmentally damaging, but OptiJoule overcomes this by efficiently and effectively processing µW to mW of energy from light, vibration ...

Toshiba has established a European high-voltage laboratory in Duesseldorf for automotive and industrial markets. “In line with the company’s shift in focus towards more power-related products, Toshiba invested this year in infrastructure and equipment such as high voltage power sources, loads and measuring equipment,” said Toshiba, The lab will will support European customers, particularly for silicon carbide and gallium nitride technologies used ...

Infineon has introduced a dual-channel smart gate driver for high-side load switches, design to control heavy loads in a 48 V board net through an SPI interface. Called 2ED4820-EM and ruggedised against vehicle transients, it can tolerate negative voltages at Vbat down to -90V and voltages up to +105V. Bus current sensing is included, with the amplifier compatible with both ...

Recom has created a range of unregulated dc-dc converters designed to provide voltages tuned for GaN, SiC or silicon gate driving. Called the RA3 series, they are 23.4 x 15 x 8.5mm LGA surface-mount parts offering one of five output combinations: +7 and -1V +15 and -3V +20 and -5V single +8V single +9V “These values cover the requirements of IGBTs, silicon ...

P-Duke has introduced medical grade PSUs that deliver 150W convection cooled, 180W fan cooled, and boost to 220W for 5s. The MAD180 series has 2xMOPP insulation and leakage current <100µA. “Being certified with EIC/EN/ANSI 60601-1 makes this supply suitable for any safety demanding type BF medical application,” said Luso, with is representing P-Duke in the UK. “It comes in 2 x ...

Korean transistor maker Magnachip has announced today 11 600V super-junction mosfets Describing them as ‘2.5th generation’, they are claimed to have lower switching loss and better power efficiency than its previous devices. Rds(on) varies between 190 and 580mΩ and packages include DPAK TO-220F and TO-220SF (see photo). A gate-source Zener diode is embedded to protect against electrostatic discharge and other surges. ...

Audi RS Q e-tron is a fuel-electric series hybrid made for the Dakar cross-desert race, which finishes today. In series hybrids, all drive is via electricity, there is no rotating mechanical link between heat engine and wheels. Just like a diesel-electric railway train, the intervening electric drive allows the fuel engine to run continuously at its most efficient operating point ...

XP Power is aiming at IT, industrial electronics and robotics with 60W ac-dc power supplies that can operate from 90-305Vac. This range suits them suitable to factory or roadside equipment running from four-wire three-phase 480Vac (277Vac nominal), or running from single-phase 110 or 230Vac. Called the VCB60 series, there are eight devices with regulated outputs ranging across 5Vdc to 54Vdc. ...

Infineon announced source-down packaged power mosfets earlier today in which it flipped the die to improve transistor performance. Alongside the part announcement it released a diagram and its reasons for what it did. The source-down mosfet is on the right, and the more conventional device on the left. According to Infineon: The source-down package (1) is externally the same as the ...

Silanna Semiconductor has released a 33W charger reference design built around its SZ1131 and silicon power FETs. This follows a larger 65W design released last year. The active clamp fly-back design, called RD-23, “provides a route to delivering performance that matches or exceeds that of commercially available 30W GaN-based chargers at a cost more readily associated with conventional silicon designs,” claimed the ...
