STEVAL-ISA111V1, Wide Range Single Output Demonstration Board based on the VIPER26HN. The STEVAL-ISA111V1 demonstration board is a 12 V, 1 A power supply set in non-isolated flyback topology using the VIPER26HN, the new offline high voltage converter. The features include an 800 V avalanche rugged power section, PWM operation at 115 kHz with frequency jittering for lower EMI, current limiting with adjustable set point, on-board soft-start, a safe auto-restart after a fault condition and a low standby power. The protections include thermal shut-down with hysteresis, delayed overload protection and open loop failure protection
