Mains dimmable buck-boost LED driver IC 5 Ohm/450 V

This device is no longer available. Please see the EOL notice.

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)

Extended IC lifetime
