This is a high-performance, adjustable constant current, and PWM dimmer project. It provides accurate output constant current and PWM control. The circuit regulates the current flowing through a LED/LED array to maintain the desired level of light output.  The board consists of CAT4101 LED driver chip and LTC6992-1 PWM generator chip. The CAT4101 is a […]
