... Figure 29. Switching Frequency vs. R ADP2386 SYNCHRONIZATION To synchronize the ADP2386, connect an external clock to the SYNC pin. The external clock frequency can be in the range of 200 kHz to 1.4 MHz. During synchronization, the regulator operates in continuous conduction mode (CCM), and the rising edge of the switching waveform runs 180° out of phase to the rising edge of the external clock ...
