Quasi-Resonant Buck Controller for Precise Current Regulation and Wide Analog Dimming NCL30076 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 Semiconductor’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. PWM dimming control is also provided in case that constant LED color temperature is required.
