TEA1401T is a SOPS controller IC for power plug launched by Philips Semiconductors. The chip can be powered directly from the rectified universal mains, and it integrates a high voltage power switch, which has high power efficiency and is a slim-line electronic power plug.
The Philips TEA1401T is a Self Oscillating Power Supply (SOPS) controller IC designed for compact power plugs supplying up to 20 W. It operates directly from the rectified universal mains (90 to 280 V AC) and includes an integrated high-voltage power DMOS FET rated at 625 V/1 A. The device implements major design features such as current regulation at the primary side, eliminating the need for opto-couplers or secondary electronics.
