LM3431EVAL, Evaluation Board using LM3431 boost voltage regulator and multi-channel LED current controller
Referenzdesign von: Texas Instruments
LM3431EVAL, Evaluation Board using LM3431 a combination switching boost voltage regulator and multi-channel LED current controller. The LM3431 Evaluation Board is designed to drive 4 parallel strings of 8-series LEDs at 140mA per string from an input voltage range of 8V to 18V. The boost switcher regulates LED cathode voltage for optimum efficiency, while allowing the output voltage to vary according to the LED forward voltage
