STMicroelectronics, AC-DC Converter 3A, 4.5 → 30 V 16-Pin, SO16N VIPER318XDTR

The STMicroelectronics VIPER31 device is a high-voltage converter that smartly integrates an 800 V avalanche rugged power MOSFET with PWM current-mode control. The 800 V breakdown allows extended input voltage range to be applied, as well as to reduce the size of the DRAIN snubber circuit. The IC can meet the most stringent energy-saving standards as it has very low consumption and operates in pulse frequency modulation at light load. Overvoltage and undervoltage protections with separate and settable intervention thresholds are available at OVP and UVP pins respectively. Applications include Low power SMPS for home appliances, home automation, industrial etc.

Ultra-low input power consumption
Built-in soft-start for improved system reliability
Embedded protections with automatic restart
