Multi-Channel Power Supply LSI Series for Car Electronics

Multi-channel Power Supply IC

for Car Audio Systems

BD49101AEFS-M

General Description

Key Specifications

 Input Voltage Range:

 DCDC1(controller):

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. And it has low power mode operation or

voltage control function so that you can get ①High

Efficiency ②Low IQ and ③easiness of power supply

design.

5.5V to 25V(VIN0=BCAP)
