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)
