DATA SHEET www.onsemi.com Constant-Current Buck Regulator for Driving High Power LEDs DFN10 CASE 485C NCL30161 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 .
