40V N-Channel PowerTrench® MOSFET
General Description
This N-Channel MOSFET has been designed
specifically to improve the overall efficiency of DC/DC
converters using either synchronous or conventional
switching PWM controllers. It has been optimized for
low gate charge, low RDS(ON) and fast switching speed.
Applications
DC/DC converter
Features
12.5 A, 40 V. RDS(ON) = 9 m@ VGS = 10 V
Low gate charge (45 nC)
High performance trench technology for extremely
low RDS(ON)
High power and current handling capability
