Toshiba Adds New 4-channel High-Efficiency Linear Power Amplifier for Car Audios Featuring Maximum 45W Output

BUSINESS-WIRE-INDIA0 234


Toshiba Electronic Devices & Storage Corporation (“Toshiba”) today announced the launch of "TCB702FNG," an addition to its 4-channel high-efficiency linear power amplifiers that meet current market requirements for high efficiency. Sample shipments start today with mass production scheduled to begin in the first quarter of 2019.

With "TCB702FNG," Toshiba has improved on its technology to realize efficiency comparable with a digital high efficiency of class D amplifier in actual operating range (0.5 to 4W). Power consumption is cut by up to 80% of that for a typical class AB amplifier[1]. The new IC’s maximum output is 45W, and the IC is pin-compatible with “TCB701FNG,” the company’s high efficiency linear power amplifier with maximum 50W output.

 

The new amplifier also includes a self-diagnosis function with I2C bus control that can diagnose errors and contribute to a suitable set design by changing the detection setting for gain or time constants. It also includes full-time error detection of output DC offset voltage, which can quickly detect abnormal output offset voltage and prevent speaker burnout, improving set reliability.
