TEA2018A Datasheet PDF - ST Microelectronics

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
