- This device is no longer available. Please see the EOL notice.
- Driving LED strings from a rectified mains supply, high power factor/low-THD
- 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
