VIPER27 - Off-line high voltage converters

Description

The device is an off-line converter with an 800 V rugged power section, a PWM control, two levels of over-current protection, overvoltage and overload protections, hysteretic thermal protection, soft-start and safe auto-restart after any fault condition removal.

Features

  • 800 V avalanche rugged power section PWM operation with frequency jittering for low EMI Operating frequency:.
  • 60 kHz for L type.
  • 115 kHz for H type Standby power < 50 mW at 265 Vac Limiting current with adjustable set point Adjustable and accurate overvoltage protection On-board soft-start Safe auto-restart after a fault condition Hysteretic thermal shutdown SO16 narrow DIP-7 SO 16.
