Product overview

Description

The device is a high voltage converter, which smartly integrates an 800 V rugged power MOSFET with a quasi-resonant current mode PWM control. This IC meets severe energy saving standards as it has very low consumption and operates in burst mode under light load conditions. The device features the brown-out enabling the IC to set the switch-off and switch-on threshold independently one of each other. The quasi-resonant operation reduces the level of EMI and the quantity of components in the application.
The quasi-resonant operation reduces the switching losses and improves power conversion efficiency. The device features high level protections such as: output overvoltage, short-circuit and thermal shutdown with hysteresis. After the removal of a fault condition, the IC is automatically restarted.
  • All features

    • 800 V avalanche-rugged power MOSFET allowing ultra wide range input VAC to be achieved
    • Embedded HV start-up and senseFET
    • Built-in soft-start
    • Quasi-resonant current mode PWM controller with drain current limit (IDlim)
    • Multifunction ZCD pin:
      • Zero-current detection
      • OCP threshold (IDlim) setup
      • Output OVP (auto-restart)
      • Feed-forward compensation
    • Support isolated flyback topology with opto-coupler
    • Frequency limit:
      • 136 kHz (L type), 225 kHz (H type)
    • Less than 30 mW @ 230 VAC in no-load condition
    • Brown-out set through resistor divider
    • Short-circuit protection (auto-restart)
    • Hysteretic thermal shutdown
