which is greater than that on IN, a large resulting
reverse current may flow, potentially damaging the
AAT4601.
Printed Circuit Board Layout
Recommendations
For proper thermal management, and to take
advantage of the low R_DS(ON) of the AAT4601, a few
circuit board layout rules should be followed: V_IN
and V_OUT should be routed using wider than normal
traces, and GND should be connected to a ground
plane. For best performance, C_IN and C_OUT should
be placed close to the package pins.
Evaluation Board Layout
The AAT4601 evaluation layout follows the printed
circuit board layout recommendations, and can be
used for good applications layout.
