Renesas has introduced three 650V GaN power transistors, aimed at server power supplies and e-mobility chargers. “Designed for multi-kilowatt-class applications, these devices combine GaN technology with a silicon-compatible gate drive input,” according to the company. “Offered in TOLT, TO-247 and TOLL package options, the devices give engineers the flexibility to customize their thermal management and board design.” The result of ...

Wise Integration has released its GaN PFC (power factor correction) controller chip to production. WIW1101 is based on a 32bit MCU, said the company, and is specifically for totem pole PFCs operating in critical conduction mode (CrCM), switching at up to 2MHz and delivering between 100W and 1.5kW. Its proprietary internal algorithm “enables ZVS [zero voltage switching] across all power ...

Q-Tech has announced less accurate versions of its QT2020 and QT2021 series of space-qualified  MCXOs (microcomputer compensated crystal oscillators). “By expanding the selection of stability levels to include 50ppb and 100ppb versions, we’re able to supply with shorter lead times and at lower cost,” said Q-Tech v-p of marketing Scott Sentz. The list of options is now: ±10ppb, 0 to ...

Menlo Micro announced an 80Gbit/s PAM4 loop-back switch for testing asymmetric SerDes busses at IMS 2025, the International Microwave Symposium in San Francisco. “MM5625 delivers over 100 different configurations for the most complex SerDes bus test challenges,” according to the company. It can “support the high-speed differential signal switching required in the latest PCIe Gen 5, Gen 6, and other ...

Silicon Labs has moved to 22nm for its latest series of wireless MCUs for IoT nodes. Announced today, there are parts for Zigbee, Bluetooth and Matter-over-Thread, and for mains or battery power. SixG301 is the mains-powered (line-powered) family, where ‘x’ becomes ‘B’ for the Bluetooth LE (and Bluetooth mesh) focussed variant, or ‘M’ for multi-protocol types. Concurrent multi-protocol operation will ...

Rutronik has added a lower power Epson 32.768kHz crystal to its line up. Power saving from the FC1610BN comes from its low ESR (effective series resistance) which is typically 45kΩ at +25°C, a maximum of 60kΩ over -40 to +85°C and a maximum of 70kΩ up to +105°C. Its surface-mount package measures 1.6 x 1mm and is ceramic with a ...

Toshiba has introduced an opto-isolated SiC gate driver, that includes an active Miller clamp to tame self-turn-on behaviour in the driven device. Named TLP5814H, it is a “gate driver photocoupler suitable for driving silicon carbide mosfets in industrial equipment like inverters, uninterruptible power supplies and photovoltaic inverters which experience harsh thermal environments”, according to the company. “The Miller clamp circuit ...

Mikroe has added a smart 85V 10A stepper motor driver to its range of interchangeable ‘Click’ boards. Called Power Step 2 Click, the board “is based on the powerSTEP01, a 1/128 microstepping controller from STMicroelectronics that integrates eight n-channel mosfets with ultra-low Rds(on)”, according to Mikroe. “It features a 5MHz SPI interface, multiple safety protections, and additional control pins for ...

Vishay has created a fast opto-coupler that can operate at 25Mbit/s. Called VOIH72A, is has a digital buffering on the input and output. “The component combines a maximum pulse distortion of only 6ns, a maximum supply current of 2mA and a supply voltage range of 2.7 to 5.5V, and is fast enough to support bus systems such as SPI, as ...

Toshiba has introduced some 50Mbit/s four-channel automotive high-speed digital isolators for digital signals. It is the DCM34xx01 series, and it has been designed to typically provide 100kV/μs common-mode transient immunity, in electric vehicle on-board chargers and battery management systems. Depending on the exact part, there can be: Four forward channels Three forward and one reverse Two forward and two reverse ...
