DESCRIPTION
The TEA2262 is a monolithic integrated circuit for
the use in primary part of an off-line switching mode
power supply using a MOS power transistor.
All functions required for SMPS control under nor-
mal operating,transient or abnormal conditions are
provided.
The capability of working according to the 鈥漨aster-
slave鈥?concept, or according to the 鈥漰rimary regu-
lation鈥?mode makes the TEA2262 very flexible and
easy to use. This is particularly true for TV receiv-
ers wherethe IC provides an attractive and low cost
solution (no need of stand-by auxiliary power sup-
ply).
