Toshiba Electronics Europe has added a 45W (4Ω load) four-channel audio power amplifier to its in-car entertainment range. TCB001FNG is based upon a complementary MOS process with n and p-channel DMOS fets. Supply can vary across 6 to 18V, allowing operation while the engine is idling or cranking. “The product includes functions to detect and ...

The International Solid-State Circuits Conference’s digital architecture sub‑committee took time out to talk about artificial intelligence processors. It noted that: “Deep learning is a rapidly evolving topic, and the computational complexity of typical deep neural networks impedes their execution on resource‑scarce mobile or wearable devices. “Last year, several innovative solutions were introduced to enhance throughput ...

GaN power transistors can shrink AC‑DC power supplies and cut losses but, to get the best out of them, their gate drive waveform needs careful attention. As a German team pointed out at ISSCC, GaN transistors have a threshold voltage of ~1V, which makes them vulnerable to spurious turn‑on through the Miller capacitance, particularly when ...

Vicor’s next generation of dc-dc converter modules operate across 43-154V for rail transport and infrastructure applications. For most versions maximum output power is 240W, despite the 36 x 23mm (‘3623’) footprint. The outputs are regulated and isolated, and efficiency is up to 93%. “Modern rail infrastructure requires a wide range of DC-DC converters to power ...
