MOSFET packages save space and raise charger performance
For charging and switching applications in portable devices, Diodes Incorporated has introduced dual device combinations in thermally efficient ultra small DFN packaging. The DMS2220LFDB and DMS2120LFWB co-package a 20V P-channel enhancement mode MOSFET with a companion diode in a choice of 2mmx2mm DFN2020 and 3mmx2mm DFN3020 packages. The DMP2160UFDB, co-packages two of the same MOSFETs in the DFN2020 format.
Dialog’s system power management IC for the Intel Atom processor cuts power consumption and board space
Dialog Semiconductor plc, has launched the first in a new family of power management ICs designed to optimise the power efficiency of applications using the Intel® Atom™ processor Z5xx series which is being broadly adopted today.
