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 s.
