MB3875 Datasheet (Fujitsu Media Devices)

MB3875, DC/DC Converter

The MB3875 and MB3877 are charging DC/DC converter ICs suitable for down-conversion, which uses pulse width modulation (PWM) for controlling the output voltage and current independently.

These ICs can dynamically control the secondary battery’s charge current by detecting a voltage drop in an AC ada

MB3875 Features

* Detecting a voltage drop in the AC adapter and dynamically controlling the charge current (Dynamically-controlled charging)

* High efficiency : 95 %

* Wide range of operating supply voltages : 7 V to 25 V

* Output voltage precision (Output voltage setting resistor i
