AO4485
P-Channel Enhancement Mode Field Effect Transistor
General Description
The AO4485/L uses advanced trench technology to
provide excellent R_DS(ON) with low gate charge. This
device is suitable for use as a DC-DC converter
application.
AO4485 and AO4485L are electrically identical.
-RoHS Compliant
-AO4485L is Halogen Free
