Description:

Constant-Current Buck Regulator

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. Features
* VIN Range 6.3 V to 40 V
* Short LED Shutdown Protection: (NCL30161 Latching)
* No Control Loo

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) enab
