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 co...
