ACT4060A PCB Layout Guidelines.

Place all the power components (Diode, Inductor,

filter Capacitors) as close as possible. Use short

and wide trace between them.

If double layer PCB is used, it is good if the bottom

layer is almost fill as ground. Use ground planes for

power ground and signal ground, connect signal

ground and power ground at single point close to

the IC GND.

Arrange the power components so that the

switching current loop curl in the same direction.

Separate noise sensitive traces, such as the

voltage feedback path, compensation from noisy

sources such as inductor, diode, input capacitor.

Place

components,

such

compensation,

feedback network and boost-trap capacitors, as

close to the IC as possible.

Ceramic cap C1 is closely placed across VIN and

GND of the IC, as close as possible.
