No.10075EBT01

●Description

BD5413EFV is a 5W + 5W stereo class-D power amplifier specifically developed for low power consumption and low heat

generation applications like powered speakers. BD5413EFV employs the state-of-the-art BCD (Bipolar, CMOS and DMOS)

process technology to eliminate a turn-on resistance in the output power stage and an internal loss due to a wiring

resistance as much as possible, achieving a high performance of 80% (4W + 4W output with a load resistance of 8Ω). In

addition, BD5413EFV employs a compact power package which dissipates heat via the rear to achieve low power

consumption and low heat generation so that the need for connecting an external heat radiator can be eliminated up to a

total output of 12.8W. This product meets the needs for compact, thin sound generation systems and powerful, high-quality

sound reproduction.

●Features

1) Small output noise voltage capable of achieving a high S/N set

Input conversion noise voltage = 2.8μVrms

A bipolar differential is used for input amplifier to eliminate 1/f noise.

2) Support of power supply voltage ranging from 6V to 10.5V

A supply voltage range is supported that matches an AC adaptor or battery cell driven set.

When a set is battery driven, its operating time can be extended by means of a high performance class-D amplifier.

3) Support of low current consumption mode

A circuit current in shut-down mode is 1μA or less.

4) Built-in soft muting function for reducing pop at shut-down ON or OFF

When a signal is present, its smooth envelope waveform is realized owing to this function.

In addition, when no signal is present, pop generation is eliminated.

A transit time can be adjusted easily through the use of an external capacitor.

5) Realization of high efficiency and low heat generation

Efficiency = 80% (4W+4W (Vcc=9V, R_L=8Ω) output can be made without using an external heat radiator.)

A compact power package HTSSOP-B24 (7.8mm x 7.6mm) is employed.

6) Built-in function for reducing pop generation at disconnection from the outlet

7) Support of function for sampling frequency selection

An internal PWM sampling frequency can be selected from three frequencies (200kHz, 250kHz and 300kHz).

Countermeasures against interference (beat noise) due to a switching power source can be taken as needed.

8) Realization of high reliability

Countermeasures against short-circuits due to output terminals shorted to V_CCor ground can be taken

(support of automatic recovery).

A temperature protection circuit is incorporated (support of automatic recovery).

9) Support of ERROR pin

ERROR output takes place as a warning which indicates an error.

(short-circuits due to output terminals shorted to V_CCor ground, or IC high temperature abnormality).
