DC/DC Converter IC for Charging

Li-ion Battery

MB39A125/126

■ DESCRIPTION

MB39A125/126 is a DC/DC converter IC for charging Li-ion battery, which is suitable for down-conversion, and

uses pulse width modulation (PWM) for controlling the output voltage and current independently. This IC integrates

the build-in comparator for the voltage detection of the AC adapter, and selects the AC adapter or battery auto-

matically for power supply to the system.

Provides a wide range of power supply voltage, low standby current, and high efficiency, which makes them ideal

as a built-in charging device in products such as notebook PC.

■ FEATURES

• High efficiency : 97% (MAX)

• Built-in two constant current control circuits

• Analog control of the charging current value (+INE1, +INE2 terminal)

• Built-in AC adapter voltage detection function (ACOK, XACOK terminal)
