NCL30160DR2G

1.0A Constant-Current

Buck REGULATOR for Driving

High Power LEDs

The NCL30160 is an NFET hysteretic step−down, constant−current

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.
