Constant-Current Buck Regulator

NCL30161 Constant-Current Buck Regulator for Driving High Power LEDs The NCL30161 is a hysteretic step−down, constant−current driver for high power LEDs. Ideal for industrial and general lighting applications utilizing minimal external components. The NCL30161 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 a wide range of pulsed dimming, and a high switching frequency 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 NCL30161 is available in a DFN10 3 mm x 3 mm package.
