Description
The STEVAL-ISA115V1 evaluation board is a 12
V / 0.15 A power supply set in buck topology with
the VIPER06XS, a new off-line high voltage
converter by STMicroelectronics.
The features of the device include an 800 V
avalanche rugged power section, PWM operation
at 30 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 consumption.
Available protection features include thermal
shutdown with hysteresis, delayed overload
protection and open loop failure protection. All
protection is auto-restart mode.
