Frequently Asked Questions
What range of mains voltages does the TEA1654 support?
It supports universal mains supply operation ranging from 70 to 276 V AC.
How efficient is the power supply at partial loads or standby?
It maintains optimum efficiency through cycle skipping mode and valley switching, achieving low consumption (<3 W).
What kind of safety features are incorporated into the IC?
The TEA1654 offers multiple protections, including undervoltage (UV), overcurrent (OCP), and overtemperature protection.
Can I optimize the quasi-resonant operation without extra parts?
Yes, the design allows the drain voltage to reach zero switching even with an optimized supply CC design.
