- Reduces sound loss and noise in car audio during idling reduction –
TOKYO — (BUSINESS WIRE) — January 26, 2015 — Toshiba Corporation (TOKYO:6502) today announced the launch of “TCB001HQ,” a 4-channel power amplifier IC that improves noise tolerance in audio systems in cars with engine idling reduction systems. Samples are available now with mass production scheduled to start in March 2015.

The engines of cars with idling reduction systems often cut out, causing battery voltage to drop. By reducing the minimum operation voltage from 8V to 6V, the new power amplifier realizes stable operation and also prevents loss of sound and noise generation in car audio.
The IC improves noise tolerance with a newly developed filter circuit, and minimizes the influence of cellular phone waves on the sound. In addition, reinforced protection circuits realize higher reliability.
