Adaptive on-time maintains near-constant frequency. Eco-Mode skips pulses at light loads. 91% peak efficiency at 12V to 1.5V 14A.","working_principle":"D-CAP mode compares VOUT directly against 0.6V reference via comparator, eliminating error amplifier and compensation. Adaptive on-time adjusts based on VIN\/VOUT ratio. Eco-Mode skips switching at light load. Integrated bootstrap switch and 5V LDO simplify design.","pin_description":"
