Choose the appropriate resistor from the resistance versus frequency table Table 2 or graph Figure 7. A resistor must be placed from the FREQ pin to ground, even if an external oscillation is applied for synchronization.
Increasing switching frequency reduces the value of external capacitors and inductors, but also reduces the power conversion efficiency. The user should set the frequency for the minimum tolerable efficiency.
