| FDFMA2N028Z Integrated N-Channel PowerTrench(R) MOSFET and Schottky Diode March 2008 FDFMA2N028Z 20V, 3.7A, 68m Features MOSFET Integrated N-Channel PowerTrench(R) MOSFET and Schottky Diode General Description This device is designed specifically as a single package solution for a boost topology in cellular handset and other ultra-portable applications. It features a MOSFET with low on-state resistance, and an independently connected schottky diode with low forward voltage. The MicroFET 2x2 package offers exceptional thermal performance for its physical size and is well suited to switching and linear mode applications.
