DESCRIPTION

The TEA2262 is a monolithic integrated circuit for the usein primarypart of anoff-lineswitching mode power supply using a MOS power transistor. All functionsrequired for SMPS control under normal operating,transient or abnormal conditionsare provided.

The capability of working according to the ”master slave” concept, or according to the ”primary regulation” mode makes the TEA2262 very flexible and easy to use. This is particularly true for TV receivers wherethe IC providesanattractive andlow cost solution (no need of stand-by auxiliary power supply).
