  • Operating Voltage Range: 8.5V to 20V
  • Low Start-Up Current: < 50µA
  • Zero Current Detection (ZCD) for Transition Mode Operation
  • Overvoltage Protection (OVP)
  • Undervoltage Lockout (UVLO)
  • Soft-Start Function
  • High Peak Current Capability (Up to 1.5A)
  • Low Power Consumption in Standby Mode
  • Adjustable Output Voltage Regulation
  • Totem Pole Output Stage for Direct MOSFET Drive

Applications:

  • AC-DC power supplies
  • LED drivers
  • Industrial and consumer power systems

Package:

  • SO8 (Small Outline 8-pin package)

This information is based on the manufacturer's datasheet. For detailed electrical characteristics and application circuits, refer to the official PHI (Philips) documentation.
