The PTQB425080 provides a 275 kHz SmartSync clock signal that may be used to synchronize multiple
downstream non-isolated modules to a common frequency. Figure 10 shows a simplified block diagram of the
PTQB425080 clock signal driving the SmartSync input of two PTH08T220W modules. Synchronizing modules
powered from the same bus, eliminates beat frequencies reflected back to the input supply, and also reduces
EMI filtering requirements. These are the benefits of Smart Sync. Power modules can also be synchronized out
of phase to minimize source current loading and minimize input capacitance requirements. Figure 10 also shows
module U2 synchronized 180° out of phase with module U3 using an inverter circuit.
