| 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%)
