STEVAL-ISA081V1

STEVAL-ISA081V1 is a 12V /1A SMPS wide range demonstration board based on VIPER26. The STEVAL-ISA081V1 demonstration board is a switched mode power supply (SMPS) demonstration board and it is an isolated SMPS capable of delivering a 12W output over a wide input voltage range. It is designed for a mains application focusing on cost and size effective solutions. The STEVAL-ISA081V1 SMPS generates 12V nominal output voltage using primary regulation and it is based on the VIPER26 monolithic converter, integrating a high voltage MOSFET and PWM controller in one package.
