39A126 MB39A126

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.
