Product data sheet
The TEA1553T is a controller for a compact flyback converter, with the IC situated on the
primary side. An auxiliary winding of the transformer provides demagnetization detection
and powers the IC after start-up.
The TEA1553T operates in multi modes, see
Fig 3. Basic application
V MAINS
(1) If a 600 V MOSFET is used, the DRAIN connection can be made directly to the Vin; a
center-tap from the transformer is not necessary.
