a simple, easy-to-use, 2A synchronous step-down DC-DC converter with an input supply voltage range of 4.5V to 18V. The device integrates low RDS(ON) power MOSFETs to achieve high efficiency in a SOT23 package and build-in accurate reference voltage (0.765V by product options). The RT6218A/B adopts Advanced Constant On-Time (ACOTTM) control architecture to provide an ultrafast transient response with few external components and to operate in nearly constant switching frequency over the line, load, and output voltage range. The RT6218A operates in automatic PSM that maintains high efficiency during light load operation.
