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.

PIN FUNCTION DESCRIPTION
Pin Pin Name Description Application Information
1, 2 CS Current Sense feedback pin Set the current through the LED array by connecting a resistor from this pin to
ground.
3 GND Ground Pin Ground. Reference point for all voltages
4 VCC Output of Internal 5 V linear
regulator
The VCC pin supplies the power to the internal circuitry. The VCC is the
output of a linear regulator which is powered from VIN. A 2 uF ceramic
capacitor is recommended for bypassing and should be placed as close as
possible to the VCC and AGND pins. Do not connect to an external load.
5 ROT Off−Time Setting Resistor Resistor ROT from this pin to VCC sets the Off−Time range for the hysteretic
controller.
6 DIM/EN PWM Dimming Control &
ENABLE
Connect a logic−level PWM signal to this pin to enable/disable the power
MOSFET and LED array
7 VIN Input Voltage Pin Nominal operating input range is 6.3 V to 40 V. Input supply pin to the internal
circuitry and the positive input to the current sense comparators. Due high
frequency noise, a 10 mF ceramic capacitor is recommended to be placed as
close as possible to VIN and power ground.
8 LX Drain of Internal Power
MOSFET
The LX pin connects to the inductor and provides the switching current
necessary to operate in hysteretic mode.
