General 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 automatically 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.
