Click For Summary
External synchronization frequency refers to the ability to align a DC-DC converter's switching frequency with an external clock, typically within the range of 350-450 kHz. This synchronization helps minimize noise interference with nearby equipment. If no external clock is provided, the converter will operate at a free-running frequency within that range. Understanding this concept is crucial for optimizing performance in electronic systems. The discussion highlights the importance of synchronization in reducing potential interference.

Welcome to the PF.
It probably means that you can synchronize the DC-DC converter's switching frequency to an external clock in that frequency range. That is often done to avoid noise interference with other equipment nearby. If you don't supply a synchronizing clock, the DC-DC will free-run at some frequency in that frequency range probably.
