Description
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.
