Overview
FUJITSU SEMICONDUCTOR DATA SHEET DS04-27234-1E ASSP For Power Supply Applications (Secondary Battery) 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 for 2 batteries.
The MB39A107 provides a broad power supply voltage range and low standby current as well as high efficiency, making it ideal for use as a built-in charging device in products such as notebook PC.
s FEATURES • • • • • • Built-in low-current control circuits in two systems (supporting dy...
