SN3350
Description
The SN3350 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.
Key Features
- z Simple low parts count
- Internal 40V power switch
- Wide input voltage range: 6V to 40V
- High efficiency (up to 95% )
- Typical 1200：1 dimming rate
- Typical 5% output current accuracy
- Single pin on/off and brightness control using DC
- Up to 1MHz switching frequency
- Inherent open-circuit LED protection
- Thermal shutdown protection circuitry
Applications
- Leave floating for normal operation.(VADJ = VREF = 1.2V giving nominal average output current IOUT nom =0.1/RS )
