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 num.
