Si4884DY
Single N-Channel Logic Level PWM Optimized PowerTrench^® MOSFET
General Description
This N-Channel Logic Level MOSFET has been designed
specifically to improve the overall efficiency of DC/DC
converters using either synchronous or conventional
switching PWM controllers.
The MOSFET features 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
11.5 A, 30 V. R_DS(ON) = 0.010 Ω @ V_GS = 10 V
R_DS(ON) = 0.015 Ω @ V_GS = 4.5 V.
Optimized for use in switching DC/DC converters with
PWM controllers.
Very fast switching.
Low gate charge (typical Qg = 19 nC).
