The A80601/4 delivers ultra-high dimming ratios (up to 15,000:1 at 200Hz) with minimal output ripple, using patented Pre-Emptive Boost (PEB) control. These multi-output LED drivers offer integrated current sinks, flexible boost/SEPIC operation, and extensive protection features. The A80604 provides a modified programming range for PEB control, optimized for lower boost switching frequencies.
