General Description:
The CN5612 current regulator operates from a 2.7V to 6V input voltage range and delivers a constant current that is up to 1.2A to high-brightness LEDs, including high-brightness white LED. The LED current of CN5612 can be adjusted from 30mA to 1.2A by using an external resistor. An on-chip pass element minimizes external components while providing ± 8% output current accuracy. Additional features include over temperature protection, LED short and open protection.
The CN5612 is available in a thermally enhanced 5-pin TO252 package.
