Beschreibung

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.

Eigenschaften

  • 800 V avalanche rugged power MOSFET allowing wide range VAC input range to be covered
  • Embedded HV startup and sense-FET
  • Current mode PWM controller
  • Minimized system input power consumption:
  • Less than 30 mW @ 230 VAC in no-load condition
  • 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

Typische Anwendungen

  • Home, building and city automation
  • Connectivity
