Description
The STEVAL-ISA103V1 is a wide range input
demonstration board based on the VIPER27LN
and suitable for several consumer applications,
such as LCD or plasma TVs, some models of
DVD recorders, set-top boxes with hard disk, and
also desktop computers.
The STEVAL-ISA103V1 includes two modules:
the main power supply that provides most of the
power and is off when the application is in
standby mode and the auxiliary power supply that
provides energy for specific peripherals such as
USB ports, remote receivers, and modems.
The auxiliary power supply is also on when the
application is in standby mode and it is often
required that its input power be as low as
possible.
The STEVAL-ISA103V1meets the specifications
of a wide range of auxiliary power supplies for the
above mentioned applications and is optimized for
very low standby consumption, helping to meet
the most stringent energy-saving requirements.
