» Product Change Notification
The NCL30076 is a DC-DC buck controller for wide dimming range down to 1% by analog dimming control to relieve audible noise and flicker in PWM dimming. ON’s proprietary LED current calculation technique driven by zero input offset amplifiers performs precise constant current in the whole analog dimming range. Multi-mode operation provides high efficiency with minimized switching loss by QR at heavy load and deep analog dimming by DCM at light load.
Features   Benefits
     
  • Zero input offset Amplifiers at LED current calculator block and OTA
 
  • Precise CC regulation: <±2% at full load, <±20% at 1% load
  • QR to DCM transition by dimming condition
 
  • Wide Analog Dimming Range; 1~100%
  • PWM Dimming by PWM signal
 
  • Keep Constant LED color temperature
  • Standby mode operation
 
  • Low standby power consumption
  • Various Protections; Auto Restart (AR)
    - VDD Over Voltage Protection (OVP)
    - Short LED Protection (SLP)
    - Over Current Protection (OCP)
