MBI1824

4-Channel All-Ways-OnTM Constant Current LED Driver

MBI1824 is an instant On/Off LED driver for lighting applications and exploits PrecisionDrive™ technology to enhance its output characteristics. At MBI1824 output stage, 4 regulated current ports are designed to provide uniform and constant current sinks for driving LEDs within a large range of VF variations.

MBI1824 provides users 4-channel constant current ports to match LEDs with equal current. Users may adjust the output current from 10mA to 120mA through an external resistor, Rext, which gives users flexibility in controlling the light intensity of LEDs. In addition, users can precisely adjust LED brightness from 0% to 100% via output enable (OE) with Pulse Width Modulation.

Additionally, to ensure the system reliability, MBI1824 is built with thermal pad. The thermal pad enhances the power dissipation. As a result, a large amount of current can be handled safely in one package.
