11.1 Layout Guidelines

Carefully consider the layout of the PCB in order for the best results to be obtained.

Input and output power and ground planes provide a low-impedance path for the input and output power. For the output, the positive and negative voltage outputs conduct through wide traces to minimize losses.

A good-quality, low-ESR, ceramic capacitor placed as close as practical across the input reduces reflected ripple and ensure a smooth start-up.

The location of the decoupling capacitors in close proximity to their respective pins ensures low losses due to the effects of stray inductance, thus improving the ripple performance. This location is of particular importance to the input decoupling capacitor, because this capacitor supplies the transient current associated with the fast switching waveforms of the power drive circuits.
