FDS9945            Description

 

  This N-channel logic level MOSFET is designed to improve the overall efficiency of the DC/DC converter, using either a synchronous switch PWM controller or a conventional switch PWM controller. Compared with other MOSFET with equivalent RDS (ON) specification, the MOSFET switch speed is faster and the gate charge is lower. As a result, the MOSFET driver is simpler and safer (even at very high frequencies), and the DC/DC power supply is designed with higher overall efficiency.


FDS9945             Features

3.5 A, 60 V

RDS (ON) = 0.100 |? @ VGS = 10V

RDS (ON) = 0.200 |? @ VGS = 4.5V

Optimize the DC/DC converter for switching using pulse width modulation (PWM) controllers

Very fast switch

Low gate charge


FDS9945                Applications

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

DC/DC Converters
