ROHM BD5413EFV handbook
BD5413EFV is a 5W + 5W stereo Class-D power amplifier specifically developed for low power consumption and low heat generation applications like powered speakers. BD5413EFV employs the state-of-the-art BCD (Bipolar, CMOS and DMOS) process technology to eliminate a turn-on resistance in the output power stage and an internal loss due to a wiring resistance as much as possible, achieving a high performance of 80% (4W + 4W output with a load resistance of 8Ω). In addition, BD5413EFV employs a compact power package which dissipates heat via the rear to achieve low power consumption and low heat generation so that the need for connecting an external heat radiator can be eliminated up to a total output of 12.8W. This product meets the needs for compact, thin sound generation systems and powerful, high-quality sound reproduction.
ROHM BD5423AEFS handbook
BD5423AEFS is a 17W + 17W stereo class-D power amplifier IC, developed for space-saving and low heat-generation applications such as low-profile TV sets. The IC employs state-of-the-art Bipolar, CMOS, and DMOS (BCD) process technology that eliminates turn-on resistance in the output power stage and internal loss due to line resistances up to an ultimate level. With this technology, the IC has achieved high efficiency of 90% (10W + 10W output with 8Ω load), which is the top class in the industry. The IC, in addition, employs a compact back-surface heat radiation type power package to achieve low power consumption and low heat generation and eliminates necessity of installing an external radiator, up to a total output of 34W. This product satisfies both needs for drastic downsizing, low-profile structures and powerful, high- quality playback of the sound system.
