Evaluation Board using LM3423 boost regulator for 2 to 8-LEDs High Powered LED Driver

Evaluation Board using LM3423 low-side controller as a step-up (boost) regulator to deliver constant current to high power LEDs. The LM3423 is a high voltage, low-side NFET controller with an adjustable output current sense voltage. Output voltage regulation is based on peak current-mode control, which eases the design of loop compensation while providing inherent input voltage feed-forward compensation. The LM3423 includes a high-voltage start-up regulator that operates over a wide input range of 4.5V to 75V
