ROHM Semiconductor BD28412MUV
BD28412MUV is 9 W + 9 W stereo (or 18 W monaural under parallel connection) class D amplifier which can output power without an external heat sink. This LSI has built-in precise oscillator which generate selectable switching frequencies, so AM radio interference can be avoided. This LSI achieves lower power consumption under low output power, and suitable for speaker systems in which battery is equipped such as wireless speakers.| Part No. | BD28412MUV |

GENERAL DESCRIPTION
In addition, 2.1 Ch audio system can be achieved by master and slave operation without caring about beat noise.FEATURES
● Analog Differential Input● Low Standby Current
● Output Feedback Circuitry Prevents Sound Quality Degradation Caused by Power Supply Voltage Fluctuation, Achieves Low Noise and Low Distortion, Eliminates the Need of Large Electrolytic-Capacitors for Decoupling
● Power Limit Function (Linearly-programmable for voltage of PLIMIT)
● Selectable Switching Frequency (AM Avoidance Function)
● Synchronization Control is Supported (Selectable Master and Slave Operation)
● Parallel BTL (PBTL) is Supported
● Wide Voltage Range (VCC = 4.5 V to 13 V)
● Operate with Single Power Supply
● High Efficiency and Low-heat-generation Make the System Smaller, Thinner, and More Power-saving
● Pop Noise Prevention During Power Supply ON/OFF
● High Reliability Design by Built-in Protection Circuits - Overheat Protection - Under Voltage Protection - Output Short Protect...
