  • The device is a high voltage converter smartly integrating an 800 V avalanche-rugged power MOSFET with PWM current mode control. The power MOSFET with 800 V breakdown voltage allows the 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 as it has very low consumption and operates in pulse frequency modulation 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 a complete application to be designed with the minimum number of components.

    Key Features

    • 800 V avalanche-rugged power MOSFET allowing ultra wide VAC input range to be covered
    • Embedded HV startup and sense-FET
    • Current mode PWM controller
    • Drain current limit protection
      • 370 mA (VIPER113)
      • 480 mA (VIPER114)
      • 590 mA (VIPER115)
    • Wide supply voltage range: 4.5 V to 30 V
    • Minimized system input power consumption:
      • Less than 10 mW at 230 VAC in no-load condition
      • Less than 400 mW at 230 VAC with 250 mW load
    • Jittered switching frequency reduces the EMI filter cost:
      • 30 kHz ± 7% (type X)
      • 60 kHz ± 7% (type L)
      • 120kHz ± 7%(type H)
    • Embedded E/A with 1.2 V reference
    • Protections with automatic restart: overload/short-circuit (OLP), line or output OVP, max. duty cycle counter, VCC clamp
    • Pulse-skip protection to prevent flux- runaway
    • Embedded thermal shutdown
    • Built-in soft-start for improved system reliability
