NCL30160
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.
