Layout Considerations
For the AAT3119, the high charge pump switching
frequencies and large peak transient currents
require careful printed circuit board layout. As a
general rule for charge pump boost converters, the
three external capacitors should be located as
closely as possible to the device package with min-
imum length trace connections. Maximize ground
plane around the AAT3119 charge pump and make
sure all external capacitor are connected to the
immediate power ground plane. Alocal component
side ground plane is recommended. If this is not
possible due to layout area limitations, assure
good ground connections by the use of large or
multiple printed circuit board vias.
Refer to the basic AAT3119 evaluation board lay-
out shown in Figure 4 and the evaluation board
schematic shown in Figure 5 for an example of the
recommended charge pump layout design.
