For isolated power supply designs requiring low levels of radiated and conducted emissions, the following recommendations can help minimize emissions from SN6507-Q1 and its surrounding components:

• Ensure a push-pull isolation transformer with low parasitics, like leakage inductance and parasitic capacitances, is used to minimize common-mode currents across the isolation barrier and antenna effects in the system.

• Use low-emissions rectifier diodes with low recovery times, like PMEG200G20ELRX or equivalent.

• Configure SN6507-Q1 for its slowest slew-rate setting to minimize high-frequency content in the switching paths.

• Include a snubber circuit on the secondary-side of the isolation transformer to filter high-frequency content in the switching paths.

Using these configurations may each affect system-level efficiency. The SN6507DGQEVM can be used to evaluate these design options.
