Onsemi NCL30160

Beschreibung

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.
