Overview

FUJITSU SEMICONDUCTOR DATA SHEET DS04-27704-2E ASSP For Power Supply Applications (Lithium ion battery charger) DC/DC Converter IC for Parallel Charging MB3874/MB3876 s DESCRIPTION The MB3874 and MB3876 are parallel 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 adapter in order to keep its power constant (dynamically-controlled charging).
The charging method enables quick charging, for example, with the AC adapter during operation of a notebook PC.
The IC also enabl...
