The STEVAL-ISA113V1 demonstration board is a 12 V-0.35 A power supply set in non-isolated flyback topology using the new VIPER06HS offline high-voltage converter by STMicroelectronics.

The features of the device 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, onboard soft-start, a safe auto-restart after a fault condition and a low standby power.

The protection features available include a thermal shutdown with hysteresis, delayed overload protection, and open loop failure protection.
