Frequently Asked Questions

What is the primary function of the TEA1501?

It integrates a high voltage power switch and low voltage control circuitry for building a low power, isolated flyback converter.

How does the device regulate output voltage in burst mode?

It switches at high frequency until the Vaux voltage reaches 20V, then regulates by varying the switching period in bursts.

What protection features are included?

The TEA1501 includes under-voltage lockout, over-temperature protection, and over-voltage detection.

What is the typical low power consumption in Off mode?

The typical data off level current drain (Drn(off)) is programmed for 40 μA to 100 μA.
