Compact high power factor dimmable LED driver IC (v1)

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

Supports majority of available dimming solutions
Deep dimming level
Flicker-free dimming
Low electronic Bill Of Materials (BOM) ensuring a compact solution and small, single layer Printed-Circuit Board (PCB) footprint
Buck-boost Controller only. For use with external power FET
Excellent line regulation and load regulation and good LED output current accuracy
Efficient BCM operation with:
- No reverse recovery losses in freewheel diode
- Zero Current Switching (ZCS) and Valley switching
- Minimum inductance value and size required
- High efficiency (up to 90 %)
- 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)
