Layout Considerations
High charge pump switching frequencies and large
peak transient currents mandate careful printed
circuit board layout. As a general rule for charge
pump boost converters, all external capacitors
should be located as close as possible to the de-
vice package with minimum length trace connec-
tions. Maximize the ground plane around the
G5910 charge pump and make sure all external
capacitors are connected to the immediate ground
plane. A local component side ground plane is
recommended. If this is not possible due the layout
design limitations, assure good ground connections
by the use of large or multiple pcb via's. Refer to
the following G5910 evaluation board for an exam-
ple of good charge pump layout design.
