.. Middle Power Class-D Speaker Amplifiers Analog Input / Single End Output Class-D Speaker Amplifier No.10075EBT16 - Overview BD5445EFV is a Analog input type Class D Speaker Amplifier designed for Flat-panel TVs in particular for space-saving and low-power consumption, delivers an output power of 17W+17W. This 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 can achieve high efficiency of 91% (10W+10W output with 8Ω load).In addition, the IC is packaged in a pact 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. - Features 1) 17W stereo single-ended outputs 34W mono bridge-tied-load output 2) Wide supply voltage (From 10V to 27V) 3) Four selectable gain (14, 20, 26, 32d B) 4) Master / Slave function 5) Soft-start and Soft-mute 6) Low noise, Low distortion 7) Various protection functions (High temperature, Output short, Under voltage) 8) Small power package (HTSSOP-B28) - Applications Flat Panel TVs (LCD, Plasma), Home Audio, Desktop PC, Amusement equipments, Electronic Music equipments, etc. .rohm. © 2010 ROHM Co., Ltd.
