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 by STMicroelectronics.
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, onboard soft-start, a safe auto-restart after a fault condition and a low standby power. The protections include thermal shutdown with hysteresis, delayed overload protection, and open loop failure protection.
