FDS9945 General Description

These N Channel Logic Level MOSFET have been designed specifically to improve the overall efficiency of DC/DC converters using either synchronous or conventional switching PWM controllers. The MOSFET feature faster switching and lower gate charge than other MOSFET 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.

Key Features

3.5 A, 60 V
R_DS(ON) = 0.100Ω @ V_GS = 10 V
R_DS(ON) = 0.200Ω @ V_GS = 4.5 V
Optimized for use in switching DC/DC converterswith PWM controllers
Very fast switching
Low gate charge

Application

This product is general usage and suitable for many different applications.
DC/DC Converters
