Table 3.
The TEA1501 contains a high voltage power switch, a high voltage start-up circuit and low
voltage control circuitry on the same IC. Together with a transformer and a few external
components a low power, isolated, flyback converter can be built, see
system of the TEA1501 operates in a Burst mode. During each burst period the output
voltage is regulated to a desired voltage level.
