  • Supports the “Blue Angel” Standard.
  • Low Start-up Current (9uA).
  • Low Operating Current (3mA).
  • Leading-Edge Blanking.
  • Constant Output Power Limit.
  • Universal Input.
  • Built-in Synchronized Slope Compensation.
  • Current Mode Operation.
  • Cycle-by-cycle Current Limiting.
  • Under Voltage Lockout (UVLO).
  • Programmable PWM Frequency with Frequency Hopping.
  • VDD Over Voltage Protect.
