80V N-Channel Dual 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.
These MOSFETs feature faster switching and lower
gate charge than other MOSFETs with comparable
R_DS(ON) specifications. The result is a MOSFET that is
easy and safer to drive (even at very high frequencies),
and DC/DC power supply designs with higher overall
efficiency.
Features
3.4 A, 80 V.
RDS(ON) = 74 mΩ @ VGS = 10 V
RDS(ON) = 84 mΩ @ VGS = 6 V
• Fast switching speed
• Low gate charge (13nC typ)
• High performance trench technology for extremely
low RDS(ON)
• High power and current handling capability
