- Integrated MOSFET (5 Ω /450 V)
- Supports most available dimming solutions
- Deep dimming level
- Flicker-free dimming
- Low component count ensuring a compact solution and small, single layer Printed-Circuit Board (PCB) footprint
- Excellent line regulation and load regulation and good LED output current accuracy
- Hotaru current control
- Internal thermal foldback
- Efficient BCM operation with:
- Minimal recovery losses in freewheel diode
- Zero Current Switching (ZCS) and Valley switching for turn-on of switch
- Minimal inductance value and size required
- High efficiency (up to 90 %)
- Ultra low IC current during operation (< 200 μA)
- Auto-recovery protections:
- UnderVoltage LockOut (UVLO)
- Cycle-by-cycle OverCurrent Protection (OCP)
- Internal OverTemperature Protection (OTP)
- Output OverVoltage Protection (OVP)
- Output Short Protection (OSP)
