Middle Power Class-D Speaker Amplifier Series

17W+17W

Class D Speaker Amplifier for Digital Input

BD28623MUV

General Description

Key Specifications

 Supply Voltage:

BD28623MUV is a Class D Speaker Amplifier designed for

Flat-panel TVs in particular for space-saving and

low-power consumption. This IC delivers an output power

of 20W+20W. This IC employs state-of-the-art Bipolar,

CMOS, and DMOS (BCD) process technology. With this

technology, the IC can achieve high efficiency. In addition,

the IC is packaged in a compact back-surface heat-sink

type power package to achieve low power consumption

and low heat generation and to eliminate need for external

heat-sink. With this package, total output power is only

34W as compared to 40W total output power of package

with external heat-sink This product satisfies all needs for

drastic downsizing, low-profile structures and powerful

high quality playback of sound systems.

-25°C to +85°C

Package

VQFN024V4040

W(Typ) x D(Typ) x H(Max)

4.00mm x 4.00mm x 1.00mm

Features

 1 Digital Audio Interface

I²S format

SDATA: 16 / 20 / 24bit

LRCLK (f_S): 32 kHz/ 44.1kHz / 48kHz

BCLK: 64f_S(fixed)

MCLK: 256f_S/ 512f_SAutomatic Identification)

 Low supply current at RESET mode.

 Slew rate controller

; No need snubber circuit (Vcc≤22V)

 Output Feedback Circuitry which prevents decrease of

sound quality caused by change of power supply

voltage, achieves low noise and low distortion, So

the large electrolytic-capacitors for Vcc bypass is able

to be eliminated.

 Variable Gain (17dB / 20dB / 26dB)

 Wide power supply voltage range (8.5V to 24V)

 High efficiency, low heat

VQFN024V4040

Typical Application Circuit

SP ch1

(Lch)

SP ch2

(Rch)

 Pop noise prevention at power supply on / off

 Soft Muting Technology

 High reliability design by built-in protection circuits

- Overheat protection

- Under voltage protection

- Output short protection

- Output DC voltage protection

- Clock stop protection (MCLK, BCLK, LRCLK)

 Small package (VQFN024V4040)

Applications

Flat Panel TVs (LCD, Plasma)

Home Audio (Sound Bar)

Amusement Equipment

Electronic Music Equipment

Desktop PC, etc.
