Description

The TEA1401T is a Self Oscillating Power Supply (SOPS) controller IC that operates directly from the rectified universal mains. It is implemented in the BCD power logic 750 V process and includes the high voltage power switch making an integrated single-switch flyback converter.Dedicated circuitry for high power efficiency is built-in,which makes a slim-line electronic power plug concept possible.

The basic function is a galvanically isolated, combined current and voltage source. No electronics are required at the secondary side of the transformer. Implementation of the TEA1401T renders a simple, small and accurate battery charger system. The TEA1401T is capable of self starting directly from the high voltage mains line.
