Features
Description
This board implements a 15 W single-output wide
range mains power supply to be used as an
auxiliary adapter in applications such as LCD,
plasma or LED TVs, desktop computers, etc.,
when the main power supply is OFF or in standby
mode and the auxiliary power supply must
provide energy only to some specific parts of the
equipment such as USB ports, remote receiver,
etc.
The board uses the new VIPER37LE, an offline
high voltage converter from the VIPerPlus family,
specifically designed for fixed frequency flyback
converters, which combines a high-performance
low voltage PWM controller chip and a max. 4.5 Ω
R
MOSFET in the same package.
The application is optimized for less than 30 mW
standby consumption and meets the EPA 2.0
limits, therefore helping to meet the most stringent
energy saving requirements.
The board implements several protections that
considerably increase end-product safety and
reliability: overload protection, overvoltage
