TEA2019 - CURRENT MODE SWITCHING POWER SUPPLY CONTROL CIRCUIT

STMicroelectronics

General Description

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.

Key Features

: High stability regulation loop. Automatic input voltage feed-forward in discontinuous mode fly-back. Automatic pulse-by-pulse current limitation. Typical.
