Preliminary specication
Power plug for the universal mains
TEA1401T
FEATURES
Designed for compact 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 component count
Combines 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
20-pin SO medium-power package.
GENERAL 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.
