STEVAL-ISA115V1:12 V, 150 mA non-isolated buck converter using VIPer™ Plus - VIPER06XS

The STEVAL-ISA115V1 demonstration 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.
