onsemi NCL35076AADR2G SOIC8 Display Driver, 5 V

The ON Semiconductor NCL35076 is a DC−DC buck controller for wide dimming range down to 1% by analogy 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 analogy dimming range.
