DESCRIPTION
The TEA2262is a monolithicintegrated circuit for
the useinprimarypartof anoff-lineswitchingmode
power supply using a MOSpower transistor.
All functionsrequired for SMPS control under nor-
mal operating,transientorabnormalconditionsare
provided.
The capabilityof workingaccordingto the ”master-
slave” concept, or according to the ”primary regu-
lation” modemakesthe TEA2262very flexible and
easy to use. This is particularly true for TV receiv-
ers wheretheIC providesanattractiveandlowcost
solution (noneed of stand-byauxiliary power sup-
ply).
