Single output 12V/4 W, wide input range non-isolated flyback evaluation board based on VIPER06HN

The board uses the new VIPER06HN, a new offline high voltage converter from the VIPerPlus family by STMicroelectronics. The VIPER06 is specifically designed for fixed frequency flyback converters, combining a high-performance low voltage PWM controller chip and a max. 32 Ω RDS(on), 800 V BV(DSS), avalanche-rugged Power 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 STEVAL-ISA112V1 demonstration board implements several forms of protection that considerably increase end-product safety and reliability: overload protection, feedback disconnection, thermal shutdown.
