- Wide input voltage range：8V to 40V.
- Up to 1.5A output current.
- Output current limit protection.
- Over temperature protection.
- Single pin on/off and brightness control using DC
Voltage or PWM.
- Typical 5% output current accuracy.
- Inherent open-circuit LED protection.
- High efficiency (up to 97% ).
- Adjustable LED constant current.
