FREQUENCY ADJUST/SYNCHRONIZATION/SHUTDOWN
The switching frequency of LM3488 can be adjusted between 100kHz and 1MHz using a single external resistor.
This resistor must be connected between FA/SYNC/SD pin and ground, as shown in Figure 27. See Typical
Performance Characteristics to determine the value of the resistor required for a desired switching frequency.
