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.
The capability of working according to the “master-slave” concept, or according to the “primary regulation” mode makes the TEA2260/61 very flexible and easy to use. This is particularly true for TV receivers where the IC provides an attractive and low cost solution (no need of stand-by auxiliary power supply). See application note AN376/0490 for detailed information.
