MB39A114 DC/DC Converter IC

The MB39A114 is a DC/DC converter IC of pulse width modulation (PWM) type for charging, capable of independently controlling the output voltage and output current. It is suitable for down conversion. MB39A114 can dynamically control the secondary battery’s charge current by detecting a voltage drop .

MB39A114 Features

* Built-in constant current control circuit in 2-system.

* Analog control of charge current value is possible. (+INE1 terminal and +INE2 terminal)

* Built-in AC adapter detection function (When VCC is lower than the battery voltage +0.2 V, output is fixed in the off.)
