Class-D Speaker Amplifier

BD5445EFV

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 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.

●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, 32dB)

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.
