MB3874 - DC/DC Converter

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.

Features

  • Detecting a voltage drop in the AC adapter and dynamically controlling the charge current (Dynamically-controlled charging).
  • High efficiency : 93 %(In reverse-current preventive diode).
  • Wide range of operating supply voltages : 7 V to 25 V.
  • Output voltage precision (Built-in output voltage setting resistor ) : ± 0.8 % (Ta = + 25 °C).
  • High precision reference voltage source : 4.2 V ± 0.8 % (Continued) s.

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.
