Nisshinbo R1580N 34V Constant-Current LED Driver Controller

Nisshinbo R1580N 34V Constant-Current LED Driver Controller is an excellent concept for a wide range of applications using LED driver control gear. The R1580N consists of a linear dimming controller using a PWM input signal, a thermal shutdown circuit, and an undervoltage lockout circuit. The controller provides a constant current with a source that eliminates changes in current due to variations in forwarding voltage, resulting in a constant LED brightness. The R1580N eliminates flickering and EMI noise issues. A flicker-free wide-dimming constant-current LED driver can be configured by only adding an Nch MOSFET, a current sensing resistor, and capacitors to the R1580N. The R1580 has an exceptionally wide dimming range from 100% to 1.0% or even to 0.5% brightness level.
