Description
The IS31LT3360 is a continuous mode inductive step-down converter, designed for driving a single LED or multiple series connected LEDs efficiently from a voltage source higher than the LED voltage.
Features
- Up to 1.2A output current.
- High efficiency (up to 98% ).
- Wide input voltage range: 6V to 40V.
- Internal 40V power switch.
- Simple low parts count.
- Typical 3% output current accuracy.
- Single pin on/off and brightness control using DC voltage or PWM.
- Up to 1MHz switching frequency.
- Inherent LED open-circuit/short-circuit protection.
- Thermal shutdown protection circuitry.
- Typical 1200：1 dimming ratio.
