The ADP2165/ADP2166 are high efficiency, current mode control, step-down dc-to-dc regulators with an integrated 19 mΩ high-side FET and a 15 mΩ synchronous rectified FET. The ADP2165/ADP2166 combine a small size, 4 mm × 4 mm LFCSP package with an accurate current limit, resulting in a smaller inductor size and a high power density, point of load solution.
