DC/DC converter IC for Charging Li-ion battery
MB39A134
■ DESCRIPTION
The MB39A134 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 charge
voltage and current independently.
MB39A134 has a A C adapter detection compar ator i ndependent of the DC/DC con verter controller, and can control the source of po wer supply to a system.
It suppor ts a wide input v oltage r ange, enables lo w current consumption in standby mode, and can control the charge
voltage and charge current with hi...
