ASSP For Power Supply Applications (Lithium Ion Battery Charger) DC/DC Converter IC For Parallel Charging

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 batterys charge current by detecting a voltage drop in an A 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 enable parallel charging, or charging two batteries at the same time, dramatically reducing the charging time. With an on-chip output voltage setting resistor which allows the output voltage to be set at high precision, these ICs are best suited as internal Battery Chargers for notebook PCs. The MB3874 support 3-cell battery and the MB3876 support 4-cell battery. By Fujitsu Microelectronics, Inc.
