Toshiba Introduces Class-D Audio Power Amplifier, First Member of New Family Designed for Audio Consumer Electronics Applications

New Device Combines High Output Power, High Fidelity, and High Efficiency Without a Heat Sink; Enables Creation of Smaller, Lighter and/or More Powerful Audio End Products

SAN JOSE, Calif., July 10 -- Toshiba America Electronic Components, Inc. (TAEC)*, a leader in semiconductor solutions for digital consumer products, today announced the introduction of its first Class-D audio power amplifier based on bipolar, complementary metal oxide semiconductor and double-diffused metal oxide semiconductor (BiCD) technology. Designated TB2924FG, the new audio power amplifier is the first member of a new family of Class-D power amplifiers targeted at audio consumer electronics applications, including TV, home audio and portable audio applications.

"The TB2924FG offers a compelling solution for a wide range of audio power applications with its single power supply design, surface-mount package and high-efficiency operation for up to 21 watts (W) x 2 bridge-tied load (BTL) channels," said David Cruikshank, business development manager for digital consumer products in the ASSP Business Unit at TAEC. "This new device will enable the creation of smaller, lighter and/or more powerful end products. With TB2924FG, Toshiba has established a high standard of excellence for future products in its Class-D audio power amplifier family." Mr. Cruikshank noted that the new Class-D IC complements Toshiba's family of Class-AB audio power amplifiers.

Highlights of the TB2924FG include the following:

o Provides high output power at 8 ohms with 21W x 2BTL amplifier channels typical at 20 volts (V) and 10 percent total harmonic distortion (THD)

o Provides high performance at 4 ohms with 19.5W x 2 BTL amplifier channels typical at 15V and 10 percent THD

o Provides high efficiency without a heat sink for up to 10.5W x 2 BTL amplifier channels with 88 percent efficiency typical at 8 ohms, 15V and 10 percent THD

-- Lower power consumption and reduced heat generation compared to Class-AB amplifiers

-- Allows the design of end products with less weight and smaller footprints

-- Extends operating time in battery-operated applications

o Features a single power supply design with operating voltage of 11.4V to 20V (at 8 ohms) and 11.4V to 18V (at 4 ohms) at a temperature range of -20 degrees to 75 degrees Celsius

o Has low standby current of 0.2 milliamperes typical

o Features built-in standby and muting switching functions

o Features built-in master and slave oscillation control, allowing multiple units to be used together

o Provides protective circuitry against output load short circuits and thermal overstress with thermal automatic gain control features

o Housed in a small surface-mount Lead(Pb)-Free (1) HSOP36 package available in tape and reel for manufacturing efficiency

Pricing and Availability

Samples are currently available and the device is in volume production. TB2924FG is priced at $2.00 each in 10,000-piece quantities. For qualified opportunities, Toshiba offers an evaluation board and a reference design with gerber data.
