SD46102A
2A, 18V,500KHz SYNCHRONOUS STEP-DOWN DC-DC CONVERTER

    The SD46102A is a high efficiency, synchronous step down DC-DC converter with low impedance internal MOSFET. The operating input voltage range is from 4.5V to 18V,and the output voltage range is from 0.6V to 5V and achieve up to 2A continuous output current with excellent load and line regulation performance.

    The SD46102A works in Constant On-Time (COT) mode control which can support very fast transient response, and adopts internally compensation to minimize and ease the requirements of external components.

    The SD46102A is offered in SOT-23-6L package and greatly reduced the area of PCB.
