FDS4935BZ
Dual 30 Volt P-Channel PowerTrench MOSFET
tm
General Description
This P-Channel MOSFET has been designed
specifically to improve the overall efficiency of DC/DC
converters using either synchronous or conventional
switching PWM controllers, and battery chargers.
These MOSFETs feature faster switching and lower
gate charge than other MOSFETs with comparable
RDS(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
x –6.9 A, –30 V. RDS(ON) = 22 m: @ VGS = –10 V
RDS(ON) = 35 m: @ VGS = – 4.5 V
x Extended VGSS range (–25V) for battery applications
x ESD protection diode (note 3)
x High performance trench technology for extremely
low RDS(ON)
x High power and current handling capability
