Sales Briefcase
  • The device is an off-line converter with an 800 V rugged power section, a PWM control, double levels of overcurrent protection, overvoltage and overload protections, hysteretic thermal protection, soft-start and safe auto-restart after any fault condition removal. Burst mode operation and device very low consumption helps to meet the standby energy saving regulations. The quasi-resonant feature reduces EMI filter cost. Brown-out and brown-in function protects the switch mode power supply when the rectified input voltage level is below the normal minimum level specified for the system. The high voltage start-up circuit is embedded in the device.

    Key Features

    • 800 V avalanche rugged power section
    • Quasi-resonant (QR) control for valley switching operation
    • 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
