TEA2019 - ST Microelectronics

TEA2019 CURRENT MODE SWITCHING POWER SUPPLY CONTROL CIRCUIT

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 TEA2018Abut with synchronization capability by internal PLL. It is particularly suitable for applications where oscillator synchronization is required. PIN CONNECTIONS DIP 14 (Plastic package) ORDER CODE : T.

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, micro-computers and industrial applications. For more details, see application note AN406/0591. . . .
