DESCRIPTION
The SiP280X family includes six high-speed, low power
consumption, BiCMOS Current Mode Controllers.
integratedcircuitscontainallofthe controland drivefunctions
required for off-line and dc-to-dc current-mode switching
power supplies. Their advanced architecture enables the
implementation of full-featured designs with minimal external
parts count.
These
The SiP280Xfamily controllers are available in both standard
and lead (Pb)-free, SO-8 and TSSOP-8 packages, and are
rated for operation over the industrial temperature range of
--40 to 85
