Published:2011/7/8 3:03:00 Author:chopper | Keyword: 1W, high power, LED, driving circuit | From:SeekIC

Overview :　　CN5611 is a current modulation circuit under 2.7V to 6V,its constant output current is up to 800mA, and it can be used to drive various LEDs including white LEDs.Current on the LED end of CN5611 is through an external resistor to set the current range of 30mA to 800mA. Integrated chip contains power transistors,which greatly reduces the number of external components.Other functions include chip over-temperature protection, LED short/open circuit protection. CN5611 adopts 5 pinned SOT89 package whose cooling capacity is good.
