    • Less than 400 mW @ 230 VAC with 250 mW load
  • Limiting current with adjustable set point
  • Jittered switching frequency to reduce the EMI filter cost:
    • 60 kHz ±4 kHz (L type)
    • 115 kHz ±8 kHz (H type)
  • Embedded error amplifier
  • Hysteretic thermal shutdown
  • Built-in soft-start for improved system reliability
  • Protections with automatic restart: overload/short-circuit (OLP), feedback loop disconnection

The VIPER26 device is a smart high voltage converter that integrates an 800 V avalanche-rugged power MOSFET with PWM current mode control. The power MOSFET with 800 V breakdown voltage allows an extended input voltage range to be applied, as well as the size of the DRAIN snubber circuit to be reduced.

This IC meets the most stringent energy-saving standards with very low consumption and burst mode operation under light load.

The design of flyback, buck and buck boost converters is supported. The integrated HV startup, sense-FET, error amplifier and oscillator with jitter allow complete application designs with a minimum number of components.
