| CN5612 |
| Low-Dropout High-Power LED Driver |
|
| |
| 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. |
