This device is suitable for applications that must be compliant with energy saving regulations and where the PFC preregulator works as the master stage.

Features:

• Onboard 700 V startup source
• Fast “bi-directional” input voltage feedforward (1/V2correction)
• Accurate adjustable output overvoltage protection
• Protection against feedback loop disconnection (latched shutdown)
• Inductor saturation protection
• AC brownout detection
• Low (≤ 100 μA) startup current
• 6 mA max. operating bias current
• 1% (@ TJ= 25 °C) internal reference voltage
• -600/+800 mA totem pole gate driver with active pull-down during UVLO

Applications:

• PFC pre-regulators for:
  • High-end AC-DC adapter/charger
  • IEC61000-3-2 or JEITA-MITI compliant SMPS, in excess of 400 W
  • SMPS for LED luminaires
