Maxon has introduced a controller board for brushed DC and brush-less dc motors up to 1,800W (30A) continuous duty and 3,600W (60A) peak, designed for integrating inside products. Operation is across 10 to 60V and -30 to +25 °C (+75°C with derating). Called ESCON2 Module (part 783722), it is a four-quadrant device that can drive and brake in both direction, ...

Innoscience Technology has launched a 100V bi-directional GaN-on-silicon bi-directional transistor, intended to replace a pair of back-to-back mosfets for turning a power rail on and off. It “can be employed in 48V or 60V battery management systems, as well as for high-side load switch applications in bidirectional converters and switching circuits in power systems”, according to the company, which sees ...

Toshiba has introduced a 60V p-channel mosfet rated at 60V and 90A continuous current, with AEC-Q101 qualification for automotive use. Called XPH8R316MC (90A), the company sees it being used in vehicles, in load switches, electronic relays and motor drives. A similar part, XPH13016MC, is the same except rated at 60A. In both cases, pulse rating is double the continuous current ...

Power Integrations has announced the fifth generation of its InnoSwitch isolated fly-back ac-dc converter ICs, which removes the need for primary-side active clamping when operated in zero-voltage switching (ZVS) mode. Called the InnoSwitch5-Pro family, they include 750V or 900V GaN power switches, and the company claims they can be used in converters with over 95% efficiency. “The combination of ZVS ...

LEM and Semikron Danfoss have teamed up to monitor current in automotive silicon carbide power mosfet modules. The result is ‘Nano’, a current sensor that is compatible with Semikron’s DCM SiC power modules, which are rated at 750 or 1,200V and 200 to 1,000A. “The idea behind the Nano concept was to design a core-based current sensor that could fit ...

Diodes is aiming at active matrix OLED panels with three-output power management dc-dc converter. Running from 2.9 to 4.8V, AL3565 produces: 4.6 to 5.0V (VPOS) with 0.5% accuracy at up to 500mA from a buck-boost converter -1.4 to -5.4V (VNEG) with 0.5% accuracy at up to 500mA from an inverting buck-boost converter 5.8 to 7.9V (AVDD) with 0.5% accuracy at ...

Alpha and Omega has announced a double-side-cooled 100V 197A (25°C) mosfet in a 5 x 6mm DFN package. Called AONA66916, thermal resistance form the junction to the top and bottom surfaces is 0.5 and 0.55C/W respectively. “The top-exposed DFN 5×6 package shares the same footprint as AOS’ standard DFN 5×6 package, eliminating the need to modify existing PCB layouts,” said ...

Rohm has added a lineup of 600V super-junction mosfets in 6.5 x 7 x 1.66mm SOT-223-3 packaging. “In recent years, power supplies for lighting and motors for pumps are required to be smaller as devices become more sophisticated – spurring the demand for compact mosfets that are essential for switching operation,” said the company. “Generally, however, it has been difficult ...

ABLIC, the analogue IC subsidiary of MinebeaMitsumi, has  launched a series of automotive step-down switching regulators. The S-19954/5 series is a step-down switching regulator which operates at 5.5V with a 1A output and is housed in an HSNT-8(1616)B package (which is the industry’s smallest package (*1) at 1.6 x 1.6 x t0.41mm). In addition, while the circuit configuration of conventional ...

SemiQ will be exhibiting its 1.2kV SOT-227 silicon carbide mosfet power modules at APEC, the Applied Power Electronics Conference, at the end of February. The modules come with or without a co-packaged Schottky diode, with current ratings between 30 and 113A, and on-resistance spanning 80mΩ to 20mΩ respectively (see table). The SOT-227 package is designed to be bolted to a ...
