NCL30160
1.0A Constant-Current
Buck Regulator for Driving
High Power LEDs
The NCL30160 is an NFET hysteretic stepâdown, constantâcurrent
driver for high power LEDs. Ideal for automotive, industrial and
general lighting applications utilizing 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
resistorâprogrammed constant LED current, shorted LED protection,
underâvoltage and thermal shutdown. The NCL30160 is available in a
SOICâ8 package.
