Can the Pulse-Width Modulator (PWM) frequency be synchronized to an external clock?

Some PWM converters provide the ability to synchronize the oscillator to an external clock with a frequency that is either higher or lower than the frequency of the internal oscillator. If there is no requirement for synchronization, it is typically recommended to connect the sync pin to GND to prevent noise interference. Consult the product datasheet for details on an individual product”s synchronization function.
