Beschreibung

The SSL5021 and SSL5031 are part of a new range of LED driver ICs for non–isolated, non-dimmable LED solutions. Complementing NXP’s broad GreenChip SSL family of products, the new ICs supports LED lighting applications ranging from 5 W lamp power like Candela shape up to 25 W lamp power like integrated Fixtures/Luminaires, TLED and PAR lamp shapes.

Eigenschaften

  • Driving LED strings from a rectified mains supply
  • Optimized for high power factor/low-THD operation (SSL5031)
  • Small electronic Bill of Materials (BOM) enabling a compact solution and a small, single layer Printed-Circuit Board (PCB) footprint
  • Excellent line and load regulation and LED output current accuracy (< ±3 %)
  • 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 (SSL5021BTS and SSL5031BTS only)

Typische Anwendungen

  • 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
