Description
The IS31LT3354 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 required LED voltage.
Features
- Simple low parts count.
- Wide input voltage range: 6V to 40V.
- Output Current only limited by external component selection.
- High efficiency (up to 98% ).
- Typical 1200:1 dimming ratio.
- Typical 3% output current accuracy.
- Single pin on/off and brightness control using DC voltage or PWM.
- Up to 1MHz switching frequency.
- Inherent open-circuit LED protection.
- Thermal shutdown protection circuitry.
