DC/DC Converter IC for Charging Li-ion Battery with Synchronous Rectifier
MB39A107 s DESCRIPTION
The MB39A107 is a DC/DC converter IC suitable for down-conversion, using pulse-width modulation (PWM) charging and enabling output voltage to be set to any desired level from 1 cell to 4 cells. The MB39A107 adopts output for Nch MOS drive of synchronous rectification type. The MB39A107 can be used to monitor the current in an AC adapter or battery, as it contains a current amplifier that can set an offset voltage. It can also be used for applications such as setting the charging voltages...
