The RT9284A/B is a compact, high efficient and highintegration LED driver. Internal 22V MOSFET can support2 to 5 White LEDs for backlighting and camera flashing.Highly integration and internal compensation networkminimizes as 5 external component counts. Optimizedoperation frequency can meet the requirement of smallLC filters value and low operation current with highefficiency. Internal soft start function can reduce the inrushcurrent. Tiny package type of TSOT-23-5 and TSOT-23-6packages provide the best solution for PCB space savingand total BOM cost.
