It integrates the switching FET internally (step-up topology) and supports PWM dimming for brightness control. The output voltage range of 16V to 30V covers the typical forward voltage of multi-LED series strings in notebook and monitor panels. Switching frequency is programmable to 312kHz, 625kHz, or 1250kHz, letting the designer optimise inductor size versus switching losses.
