LAYOUT PROCEDURE

To achieve high efficiency, good regulation, and stability, a well-

designed printed circuit board layout is required. Where

possible, use the sample application board layout as a model.

Follow these guidelines when designing printed circuit boards

(see Figure 1):

•

GND.

•

L1, to SW and PGND as short as possible.

•

possible.

•

Keep high current traces as short and as wide as possible.

•

Place the feedback resistors as close to FB as possible to

prevent noise pickup.

•

Place the compensation components as close as possible to

COMP.

•

Avoid routing high impedance traces near any node

connected to SW or near the inductor to prevent radiated

noise injection.
