CN5612 fiche technique
CONSONANCE
Low-Dropout High-Power LED Driver
CN5612
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.
