Published:2011/7/6 6:41:00 Author:chopper | Keyword: 5W, high-power, LED, driving circuit | From:SeekIC

overview: CN5612 is a current modulation circuit under 2.7V-6V voltage,and constant output current is up to 1.2A.It can be used to drive various LEDs including white LEDs.The current of the LED terminal of CN5612 is through an external resistor to set the current range of 30mA to 1.2A.In the inner integrated chip there are power transistors,thus greatly it reduces the number of external components.Other functions include chip over-temperature protection, LED short / open circuit protection. CN5612 adopts 5-pinned TO252 package with good cooling capacity.
