STEVAL-ISA112V1 STMicroelectronics

STEVAL-ISA112V1 Wide range non-isolated flyback demonstration board, single-output 12 V/4 W based on the VIPER06HN Data brief Features Universal input mains range: input voltage 90 - 265 V AC frequency 45 - 65 Hz Single-output voltage: 12 V at 350 mA continuous operation Standby mains consumption: < 30 mW at 230 V AC Average efficiency: > 75% Complying with EuP Lot 6 requirements STEVAL-ISA112V1 Fully protected against short-circuit Fully protected against overheating The STEVAL-ISA112V1 demonstration board Compliant to EMC norm EN55022-Class-B implements several forms of protection that considerably increase end-product safety and RoHS compliant reliability: overload protection, feedback disconnection, thermal shutdown. Description The STEVAL-ISA112V1 demonstration board implements a 4 W single-output wide range mains power supply to be used in applications such as white goods, smaller home appliances, home automation, LED driver, etc. 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 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.
