Class-D Speaker Amplifier

BD5423MUV

No.10075EBT03

●Description

BD5423MUV is a 17W + 17W stereo class-D power amplifier IC, developed for space-saving and low heat-generation

applications such as low-profile TV sets. The 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 has achieved high efficiency of 90% (10W + 10W output with 8Ω load), which is the top class in the

industry. The IC, in addition, employs a compact back-surface heat radiation type power package to achieve low power

consumption and low heat generation and eliminates necessity of installing an external radiator, up to a total output of 34W.

This product satisfies both needs for drastic downsizing, low-profile structures and powerful, high-quality playback of the

sound system.

●Features

1) A high efficiency of 90% (10W + 10W output with 8Ω load), which is the highest grade in the industry and low heat-generation.

2) An output of 17W + 17W (12V, with 4Ω load) is allowed without an external heat radiator.

3) Driving a lowest rating load of 4Ω is allowed.

4) Pop noise upon turning power on/off and power interruption has been reduced.

5) High-quality audio muting is implemented by soft-switching technology.

6) An output power limiter function limits excessive output to speakers.

7) High-reliability design provided with built-in protection circuits against high temperatures, against VCC shorting and

GND shorting, against reduced-voltage, and against applying DC voltage to speaker.

8) A master/slave function allowing synchronization of multiple devices reduces beat noises.

9) Adjustment of internal PWM sampling clock frequencies (250kHz to 400kHz) allows easy protective measures against

unwanted radio emission to AM radio band.

10) A compact back-surface heat radiation type power package is employed.

●Absolute maximum ratings

A circuit must be designed and evaluated not to exceed absolute maximum rating in any cases and even momentarily, to prevent

reduction in functional performances and thermal destruction of a semiconductor product and secure useful life and reliability.

The following values assume Ta =25℃. For latest values, refer to delivery specifications.
