PRINCIPLES OF OPERATION
0.5x conversion mode
This conversion mode is internally selected if the input to output voltage ratio is greater than two (e.g. 3.6 V to
1.5 V conversion). In the 0.5x mode, the flying capacitors and the switches always work in parallel, which
reduces the resistance of the circuit compared to the other modes. In the first cycle, the flying capacitors are
charged in series with the output capacitors. In the second cycle, the flying capacitors are connected in parallel
with the output capacitor, which discharges the flying capacitors.

0.5x Conversion Mode
1/3x conversion mode
This mode was implemented to provide high efficiency even with an input to output voltage ratio greater than
three (e.g. 5 V to 1.5 V conversion). In the first cycle, the two flying capacitors are charged in series with the
output capacitor. In the next step, the flying capacitors which are charged to VIN/3, are connected in parallel
to the output capacitor.
