Product Summary

The MBI1812 is an instant On/Off LED driver for lighting applications and exploits PrecisionDrive technology to enhance its output characteristics. At the MBI1812 output stage, sixteen regulated current ports are designed to provide uniform and constant current sinks for driving LEDs within a large range of VF variations. The MBI1812 provides users 16-channel constant current ports to match LEDs with equal current. The applications of the MBI1812 include Automotive Interior Lighting, Channel Letter, Decoration Lighting.
