NCL30160

1.0A Constant-Current

Buck Regulator for Driving

High Power LEDs

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

resistor−programmed constant LED current, shorted LED protection,

under−voltage and thermal shutdown. The NCL30160 is available in a

SOIC−8 package.
