onsemi NCL35076 Wide Analog Dimming CCM Buck Controllers are ideal for a wide dimming range down to 1% by analog dimming control. This relieves audible noise and flickers in PWM dimming. onsemi’s proprietary LED current calculation technique driven by zero input offset amplifiers performs precise constant current in the whole analog dimming range. The multi-mode operation provides low LED current ripple with a small output capacitor by CCM at heavy load and deep analog dimming by DCM at light load.
