DESCRIPTION
The TEA2018Ais an 8-pin DIPlow-cost integrated
circuit designed for the control of switch mode
power supplies.
Due to its current mode regulation,the TEA2018A
facilitates design of power supplies with following
.
High stability regulationloop
.
Automatic input voltage feed-forward in dis-
continuousmode fly-back
.
Automaticpulse-by-pulsecurrent limitation
Typical applications: VideoDisplayUnits, TVsets,
typewriters,microcomputersandindustrialapplica-
tions
Where synchronization is required, use the
TEA2019. For more details, see application
