TEA1401T Description
TEA1401T 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.
TEA1401T Key Features
- Designed for pact power plugs supplying up to 20 W
- Integrated high-voltage power DMOS FET 625 V/1 A
- Operates from all mains supplies (90 to 280 V AC)
- Major design: current regulation at the primary side (no opto-coupler, no secondary electronics)
- Low external/peripheral ponent count
- bines accurate constant-voltage source (for supply) and accurate constant-current source (for charging) in one IC
- Foldback feature
- Requires simple input filter as a result of good EMC design
- Overshoot protection (output voltage)
- Protects against under-voltage input, over-current and over-temperature
