Description
ST's power modules are highly integrated, high
efficiency switch mode converters.
The SPDC400-4W not isolated series delivers
4 W at -12 V from DC input that is the rectified
universal AC.
It is an immediate drop-in solution requiring no
additional external circuitry.
The power supply modules are suited for auxiliary
power requirements in appliance, industrial and
communication applications.
The open frame version is intended to offer a low-
cost version of ST's easy to use, compact size
power modules.
