Navitas Semiconductor has given its 650V GaN power switching ICs 66% more current capability with the introduction of the 70mΩ NV6128. “With the higher-power NV6128, we extended the effective power range to 500W for the consumer market and look beyond that to multi-kW data centre, e-mobility and new energy applications,” said company CEO and founder Gene Sheridan. According to Navitas CTO Dan ...

Diodes has created its first automotive-compliant USB 2.0 passive signal mux-demux switches with over-voltage signal and power rail protection. PI3USB4000DQ is a 2:1/1:2 switch for differential bi-directional DPDT PI3USB4002AQ is a 1:1 switch for differential bi-directional DPST switching 24Vdc withstanding is provided on one high-speed data port (‘C0’ pins), enabling them to tolerate shorts between D± and Vbus on both USB and ...

On Semiconductor announced 1,200V SiC diodes with automotive AECQ101 and industrial qualification at virtual PCIM. Of the diodes, On said: “The new design improves on the first generation SiC diodes thanks to a smaller die size and lower capacitance. NVDSH20120C, NDSH20120C, NVDSH50120C, and NDSH50120C deliver a lower forward voltage drop and a 4x increase in rated current, with a higher ...

Power Integrations is aiming at railway traction with a set of gate drivers for 130 x 140mm IGBT modules from manufacturers including Infineon, Mitsubishi, Hitachi and ABB. Numbered 1SP063xxxx1R, the drivers match the footprint of single-channel IHM IGBT-modules with 1.2 to 1.4kA outputs and 3.3kV blocking voltage. There are three boards in the set: the main driver (1SP0635D2S1R peripheral driver centre) ...

Nexperia has extended its trench Schottky rectifier range with devices rated at up to 100V and 20A in the company’s ‘CFP’ packages with an internal copper clip (right), intended to have smaller footprints than SMA, SMB or SMC diodes. “Nexperia’s trench Schottky rectifiers combine low forward voltage and low Qrr to enable efficiency at high switching speeds as needed in switch-mode ...

Power Integrations has announced a 900V version of its InnoSwitch3-AQ automotive-qualified isolated fly-back dc-dc converter IC family, and a reference design using it for a PSU that will create 12V from anywhere between 30V and 1.2kV. This huge input range is needed within the emergency dc-dc PSU built into electric vehicle traction inverters – the control-side of EV inverters is ...

Schurter has introduced a series of through-hole PCB-mount common-mode chokes for use at between 10A and 50A and up to 300Vac or 450Vdc. For single-phase applications, DKIV-1 chokes are available with ferrite or nano-crystalline cores. “Like all other aspects of electronic design, the power section is often-times built today using discrete components on printed circuit boards,” according to the company. ...

High efficiency, programmable power supplies play a vital role in helping the supply of high yield crops, in a sustainable manner to supply food around the world, writes John Stone. Cultivating crops indoors allows farmers to grow a steady supply of crops all year round and regardless of external weather conditions. LED lighting offers output control for a uniform, constant ...

Infineon has introduced 2.3kV isolated gate drivers for IGBTs and mosfets with on-the-fly switchable dual slew-rates. Branded ‘2L-SRC Compact’ and numbered ‘1ED32xx’, 10 and 18A versions are available (see table), with or without Miller clamps. Dual slew-rates are controlled by a single pin (/INF). All members of the family have two complete output stages: ‘OUT’ is always active, while the ...

Recom’s RPMH-1.5 series non-isolated switching regulators are 3.75 mm high and can supply 1.5A across -40 to +100°C without derating. Versions with nominal output voltages of 3.3, 5, 12, 15, or 24V are available, each accepting input voltages up to 60V. “Switching regulators are particularly suitable for applications where the efficient handling of high ambient temperatures plays a role in safe ...
