2. Wide input voltage range of 5V to 60V
3. Low quiescent current of 1.5mA
4. Adjustable output current from 10mA to 2A
5. Integrated current sense for accurate current measurement
6. Thermal shutdown protection for safe operation
7. Programmable soft-start to reduce inrush current
8. Small package size (HTSSOP-20)

Applications:

1. Automotive LED lighting (headlights, taillights, interior lighting)
2. Industrial LED lighting (workplace, machinery, equipment)
3. Consumer LED lighting (home, office, retail)
4. LED backlighting for LCD displays
5. LED indicator and status lighting
6. LED signage and billboards
7. Medical and dental lighting
