STEVAL-ISA110V1：12 V/12 W wide range non-isolated flyback based on the VIPER26LN
The STEVAL-ISA110V1 demonstration board is a 12 V-1 A power supply set in non-isolated flyback topology using the VIPER26LN, a new offline high-voltage converter by STMicroelectronics.
The features of the device include an 800 V avalanche-rugged power section, PWM operation at 60 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 low standby power.
Protection features include thermal shutdown with hysteresis, delayed overload protection, and open loop failure protection.
