Class D speaker amplifier LSI

( 01 Sep 2007 )

The BD5421EFS Class D stereo amplifier LSI is targeted at audio-equipped sets with strict thermal design and dimensional requirements, such as liquid crystal and plasma televisions, minicomponent stereos, power speakers, and gaming devices. The device utilizes BiCDMOS processes for minimal line resistance and output transistor ON-resistance, resulting in an industry-leading 90% efficiency. 34W (17W+17W) output is enabled using a small back-surface metal plate with excellent thermal dissipation characteristics, eliminating the need for a heat sink.
