Printed Circuit Board Layout

Recommendations

For proper thermal management and to take

advantage of the low RDS(ON) of the AAT4280, a few

circuit board layout rules should be followed: VIN

and VOUT should be routed using wider than normal

traces, and GND should be connected to a ground

plane. To maximize package thermal dispation and

power handling capacity of the AAT4280 SOT23-6/

SC70JW-8 package, the ground plane area con-

nected to the ground pins should be made as large

as possible. For best performance, CIN and COUT

should be placed close to the package pins.

Evaluation Board Layout

The AAT4280 evaluation layout follows the printed

circuit board layout recommendations, and can be

used for good applications layout. Refer to Figures 1

through 3.

Note: Board layout shown is not to scale.
