MB39A125 Datasheet (Fujitsu) - DC/DC Converter IC

MB39A125, DC/DC Converter IC

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 sel
