THEORY OF OPERATION
Figure 40. Functional Block Diagram
The ADP5600 is unique among inverting regulators in that it has
two charge pump blocks that operate in an interleaving manner.
Interleaved operation gives greatly reduced input and output
voltage ripple without sacrificing efficiency, output resistance, or
ease of use compared to inductor-based solutions. An LDO
regulates the output voltage and filters out low frequency spurious
signals.
INVERTING CHARGE PUMP OPERATION
The basic voltage conversion task is achieved using a switched
capacitor technique with two external charge storage capacitors.
An internal oscillator and switching network transfer charge
between the two charge storage capacitors. The basic principle
of the voltage inversion scheme is illustrated in Figure 41.
