DIRECT DRIVE OF THE EXTERNAL SWITCHING TRANSISTOR
* POSITIVE AND NEGATIVE OUTPUT CURRENTS UP TO 0.5A
* TRANSFORMER DEMAGNETIZATION AND POWER TRANSISTOR SATURATION SENSING
FULL OVERLOAD AND SHORT-CIRCUIT PROTECTIONPROPORTIONAL BASE CURRENT DRIVING
* LOW STANDBY CURRENT BEFORE STARTING (1.6MA)
* SYNCHRONIZATION CAPABILITY WITH INTERNAL PLL
The TEA2019 is an 14-pin DIP low cost integrated circuit designed for the control of switch mode power supplies. It has the same basic functions as the TEA2018A but with synchronization capability by internal PLL. It is particularly suitable for applications where oscillator synchronization is required.
Due to its current mode regulation, the TEA2019 facilitates design of power supplies with following f
* High stability regulation loop.
* Automatic input voltage feed-forward in discontinuousmode fly-back.
* Automatic pulse-by-pulse current limitation.
