Features and benefits
  • Driving LED strings from a rectified mains supply, low-ripple (< ±5%)
  • Small electronic bill of materials (BOM) enabling a compact solution and a small, single layer printed-circuit board (PCB) footprint
  • Efficient BCM operation with:
    • No reverse recovery losses in freewheel diode
    • Zero current switching (ZCS) and valley switching
    • Minimal inductance value and size required
    • High efficiency (up to 93 %)
    • Ultra-low IC current during operation (< 150 μA)
  • Many auto-recovery protections:
    • Undervoltage lockout (UVLO)
    • Cycle-by-cycle overcurrent protection (OCP)
    • Internal overtemperature protection (OTP)
    • Output overvoltage protection (OVP)
    • Output short protection (OSP)
    • Thermal foldback protection via a single PTC or NTC resistor
  • Excellent line and load regulation and LED output current accuracy (< ±3%)
Applications
  • Low cost non-dimmable, non-isolated retrofit LED lamps up to 25 W
  • Low cost non-dimmable, non-isolated driver modules for LED lighting up to 25 W
