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
  – 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)
• Embedded E/A with 1.2 V reference
• Protections with automatic restart: overload/.
