LED driver family eliminates audible noise with control method

LED driver family eliminates audible noise with control method
Allegro MicroSystems has announced its latest generation of advanced LED backlight drivers, the A8060x family. The device family is designed with an innovative and patented Pre-Emptive Boost (PEB) control, eliminating noise that is typically audible. PEB control in the A8060x family substantially reduces Vout ripple and eliminates the common problem of audible noise from ceramic output capacitors during PWM dimming, while also requiring less output capacitance overall.
