DESCRIPTION
The TEA2018Ais an 8-pin DIP low-cost integrated circuit designed for the control of switch mode
power supplies. Due to its current mode regulation,the TEA2018A facilitates design of power supplies with following
features :
. High stability regulation loop
. Automatic input voltage feed-forward in discontinuous mode fly-back
. Automatic pulse-by-pulse current limitation
Typical applications : Video Display Units, TV sets,typewriters, microcomputersand industrial applications

. DIRECT DRIVE OF THE EXTERNAL SWITCHING TRANSISTOR
. POSITIVE AND NEGATIVE OUTPUT CURRENTS UP TO 0.5 A
. CURRENT LIMITATION
. TRANSFORMER DEMAGNETIZATION SENSING
. FULL OVERLOAD AND SHORT-CIRCUIT PROTECTION
. PROPORTIONAL BASE CURRENT DRIVING
. LOW STANDBY CURRENT BEFORE STARTING (< 1.6 mA)
. THERMAL PROTECTION
