2011/09/ 27 Ver.2 Page 1 SPN5454 N-Channel Enhancement Mode MOSFET DESCRIPTION APPLICATIONS The SPN5454 is the N-Channel logic enhancement mode power field effect transistors are produced using high cell density , DMOS trench technology. The SPN5454 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 R DS(ON) and fast switching speed. z Power Management in Note book z Powered System z DC/DC Converter z Load Switch FEATURES PIN CONFIGURATION TO-252 PART MARKING ‹ 40V/10A,RDS(ON)=18mΩ@VGS= 10V ‹ 40V/ 8A,RDS(ON)= 20mΩ@VGS= 4.5V ‹ 40V/ 6A,RDS(ON)= 28mΩ@VGS= 2.5V ‹ Super high density cell design for extremely low RDS (ON) ‹ Exceptional on-resistance and maximum DC current capability ‹ TO-252 package design
