VIPer27 Off-Line High Voltage Converters

STMicroelectronics VIPer27 Off-Line High Voltage Converters offer an 800V rugged power section, a PWM control, and two levels of over-current protection. These STMicroelectronics voltage converters also provide overvoltage protection, overload protection, hysteretic thermal protection, soft-start, and safe auto-restart after any fault condition removal.
