... Figure 26. Peak Current Limit of Switch vs. R FREQUENCY SELECTION The ADP1614 is internally programmed to operate at either 650 kHz or 1.3 MHz. Operation of the ADP1614 (ADP1614ACPZ-650-R7) optimizes the efficiency of the device, whereas operation of the ADP1614 at 1.3 MHz (ADP1614ACPZ- 1.3-R7) enables the device to be used with smaller external components.

... ADP1614. Ceramic capacitors are preferable because of their low ESR characteristics. Alternatively, use a high value, medium ESR capacitor in parallel with a 0.1 µF low ESR capacitor, placed as close as possible to the ADP1614. The output capacitor maintains the output voltage and supplies current to the load while the ...
