The VIPER12AS-E is a low power off-line switched-mode power supply Primary Switcher. It combines a dedicated current mode PWM controller with a high voltage power MOSFET on the same silicon chip. The internal control circuit offers the benefits like large input voltage range on the VDD pin accommodates changes in auxiliary supply voltage, automatic burst mode in low load condition and overvoltage protection in HICCUP mode.
Current mode control
Auxiliary under-voltage lockout with hysteresis
High voltage start-up current source
Over-temperature, over-current and overvoltage protection with auto-restart
