BM5446EFV is a Class D Speaker Amplifier with built-in DSP (Digital Sound Processor) designed for Flat-panel TVs inparticular for space-saving and low-power consumption, delivers an output power of 20W+20W. This IC employsstate-of-the-
art Bipolar, CMOS, and DMOS (BCD) process technology that eliminates turn-on resistance in the output powerstage and internal loss due to line resistances up to an ultimate level. With this technology, the IC can achieve highefficiency of 86% (10W+10W output with 8O load). In addition, the IC is packaged in a compact reverse heat radiation typepower package to achieve low power consumption and low heat generation and eliminates necessity of external heat-sinkup to a total output power of 40W. This product satisfies both needs for drastic downsizing, low-profile structures and manyfunction, high quality playback of sound system.
