BD5445EFV-E2 Datasheet PDF - ROHM Semiconductor

●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. Withthis technology, the IC can achieve high efficiency of 91% (10W+10W output with 8Ω load).

●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.
