Rhopoint Components is to supply a 1.2kV 260A three-phase silicon carbide power module for electric vehicles. Made by Cissoid and called CMT-PLA3SB12340, it can supply its 26A at 90°C, and up to 340A at 25°C. This is a complete power module, including output-to-baseplate (5kVdc for 1min) and input-to-output (3kV for 1min) isolation, power supplies to feed the secondary side gate ...

Recom has created a wide input range 1.5 x 2inch 15W ac-dc converter that operates over part that operates over 18 – 264Vac, or 18 – 375Vdc. All parts have a 40 x 52.5mm footprint and stand 25.5mm tall. PCB versions (RAC15-xxSK/WI) have through-hole pins underneath, while the flying lead version (add /W suffix) have four 100mm wires protruding from the ...

Silanna Semiconductor has created a laser driver IC that can squeeze a 400W quad EEL (edge-emitting laser) module into 80mm2. SL2001 comes in a 14ball 1 x 3.5mm WLCSP (wafer-level chip-scale package) includes both a capacitor charging circuit and another block to dump that stored energy into the laser diode. Operating from a power source between 3 and 24V it ...

Analog Devices has created a fast power op-amp that can handle ±55V rails and ±1A outputs, with a digital control bus for setting internal parameters. Called ADHV4710, the output can swing ±52V with ±100mA loading, and its rails can vary down to ±12V. Despite being able to drive ±1300V/μs into 1nF, it is a voltage feedback amplifier, that can handle ...

Toshiba has introduced a set of industrial-grade 650V SiC mosfets in 8 x 8mm DFN packaging. Of the four new devices, the company picks TW054V65C as its poster child for low turn-on and turn-off losses: 122 ad 58μJ respectively when a pair are used in a 400V 20A half-bridge* – said to be ~55% and 25% less than the company’s ...

US car maker Rivian has signed up Infineon to supply traction inverter power modules, microcontrollers and power ICs for its ‘R2’ vehicle platform, expecting to start in 2026. The power modules will be in Infineon’s HybridPack Drive G2 format (pictured) and include both silicon and silicon carbide components. Along with these, Rivian has picked infineon’s established TC3x MCUs, not not ...

ABLIC claims that its S-19116 Series automotive high-voltage detector has the industry’s fastest detection response time of max. 6.8μs while achieving ultra-low current consumption of 2.0μA typ The detector is also claimed to significantly reduce system standby current. It comes in an  HSNT-6 (1.96×2.46×t0.5mm) package. Overvoltage protection is essential when supplying voltage from a battery through a regulator to MCUs ...

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 ...

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 ...

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 ...
