Product Summary
The BD5445EFV-E2 is a Analog input type Class D Speaker Amplifier. The BD5445EFV-E2 is designed for Flat-panel TVs in particular for space-saving and low-power consumption, delivers an output power of 17W+17W. The BD5445EFV-E2 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 BD5445EFV-E2 can achieve high efficiency of 91% (10W+10W output with 8Ω load).In addition, the BD5445EFV-E2 is packaged in a compact reverse heat radiation type power package to achieve low power consumption and low heat generation and eliminates necessity of external heat-sink up to a total output power of 34W. This product satisfies both needs for drastic downsizing, low-profile structures and powerful, high-quality playback of sound system. Applications are Flat Panel TVs (LCD, Plasma), Home Audio, Desktop PC, Amusement equipments, Electronic Music equipments, etc.
