NCL30160: LED Driver, Constant Current Buck Regulator, 1.0 A
The NCL30160 is an NFET hysteretic step-down, constant-current driver for high power LEDs. Ideal for automotive, industrial and general lighting applications utilizing the minimal external components. The NCL30160 operates with an input voltage range from 6.3 V to 40 V. The hysteretic control gives good power supply rejection and fast response during load transients and PWM dimming to LED arrays of varying number and type. A dedicated PWM input (DIM/EN) enables wide range of pulsed dimming and a high switching frequency up to 1.4 MHz allows the use of smaller external components minimizing space and cost. Protection features include resistor-programmed constant LED current, broken/open LED protection, under-voltage and thermal shutdown. The NCL30160 is available in a SOIC-8 package.
