Datasheet Multi-Channel Power Supply LSI Series for Car Electronics Multi-channel Power Supply IC for Car Audio Systems BD49101AEFS-M General Description The BD49101AEFS-M LSI is a multi-channel power supply IC that can provide all necessary supply voltages for automobile audio systems. The IC has two Switching Power Supplies (DCDC), five Regulators (REG) and a High Side switch. This single power supply system can provide the required voltages to all systems including the MCU, CD, tuner, USB, illumination, audio circuits and others. The IC system is based on switching regulator which has high efficiency then you can suppress heat of IC than before.
