20W+20W Class D Speaker Amplifier for Digital Input - BD28620MUV

BD28620MUV is a Class D Speaker Amplifier designed for Flat-panel TVs in particular for space-saving and low-power consumption. This IC delivers an output power of 20W+20W. This IC employs state-of-the-art Bipolar, CMOS, and DMOS (BCD) process technology. With this technology, the IC can achieve high efficiency. In addition, the IC is packaged in a compact back-surface heat-sink type power package to achieve low power consumption and low heat generation and to eliminate need for external heat-sink. With this package, total output power is only 34W as compared to 40W total output power of package with external heat-sink This product satisfies all needs for drastic downsizing, low-profile structures and powerful high quality playback of sound systems.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
