TEA-2261 - SWITCH MODE POWER SUPPLY CONTROLLER

Download the TEA-2261 datasheet PDF. This datasheet also covers the TEA2261 variant, as both devices belong to the same switch mode power supply controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The TEA2260/61 is a monolithic integrated circuit for the use in primary part of an off-line switching mode power supply.

All functions required for SMPS control under normal operating, transient or abnormal conditions are provided.

Key Features

  • the following functions : - Power supply start-up (with soft-start) - PWM generator - Direct power transistor drive (+1.2A, -2.0A) - Safety functions : pulse by pulse current limitation, output power limitation, over and under voltage lock-out. S. M. P. S.
