Overview

FUJITSU SEMICONDUCTOR DATA SHEET DS04-27709-4E ASSP For Power Supply Applications (Secondary battery) DC/DC Converter IC for Charging Li-ion battery MB3887 ■ DESCRIPTION The MB3887 is a DC/DC converter IC suitable for down-conversion, using pulse-width (PWM) charging and enabling output voltage to be set to any desired level from one cell to four cells.
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 MB3887 provides a broad power supp...
