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.
