MB39C308 - Fujitsu

MB39C308 6ch DC/DC Converter IC

The MB39C308 is a 6ch DC/DC buck converter LSI, which integrates all of necessary power supplies for UltraMobile PC powered by 2-cell Li-ion battery. And the MB39C308 uses current mode topology with N-channel synchronous rectification to realize high conversion efficiency. The MB39C308 is the Power Management IC supporting the LPIA(Low Power Intel Architectu.
