  • The STEVAL-ISA119V1 is a dual output buck demonstration board using the VIPER16LD, a new off-line high voltage converter by STMicroelectronics which has been specifically developed for non-isolated SMPS.

    Output regulation is easily achieved through a voltage divider to the output voltage.
    The VIPER16LD can work with or without an external supply. In the former case, very low standby consumption is possible(< 50 mW at 265 Vac) while in the latter case, the cost and complication of the IC supply network may be reduced.
    The other features of the device include an 800 V avalanche-rugged power section, PWM operation at 60 kHz with frequency jittering for lower EMI, limiting current with adjustable set point, on-board soft-start and safe auto-restart after a fault condition.
    The available protection features are thermal shutdown with hysteresis and delayed overload protection.

    Key Features

    • Input voltage range (VIN): 90 VRMSto 265 VRMS
    • Output voltage 1 (VOUT1)= 12 V
    • Max output current 1: (IOUT1) = 0.1 A
    • Output voltage 2: (VOUT2) = 5 V (through LDO)
    • Max output current 2: (IOUT2)= 0.05 A
    • Precision of output regulation ΔVOUT_LF= ±5%
    • High frequency output voltage ripple ΔVOUT_HF= 50 mV
    • Max ambient operating temperature TA= 60 °C
