Product Overview

The NCL30160DR2G is a 1.0A constant-current Buck Regulator for driving high power LEDs. The NFET hysteretic step-down driver operates with an input voltage range from 6.3 to 40V. 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 1.4MHz allows the use of smaller external components minimizing space. Protection features include resistor-programmed constant LED current, shorted LED protection, under-voltage and thermal shutdown.
  • Integrated 1.0A/50mΩ MOSFET
  • Short LED shutdown protection
  • No control loop compensation required
  • Adjustable LED current
  • Single pin brightness and enable/disable control using PWM
  • Supports all ceramic-output capacitors and capacitor-less outputs
  • Thermal shutdown protection
  • Capable of 100% duty cycle operation
  • Externally adjustable LED current
  • Dedicated EN/DIM pin
  • Ability to use with a wide range of power supplies
  • High efficiency and high power solution
  • High switching frequency allows the use of small inductors
  • Ease of design and minimal external components
  • Flexibility to design for different types and number of LEDs
  • Allows easy PWM dimming
  • Small size and reduced component count
