Mingjiada Electronics Supply ADI ADP2165 And ADP2166 Series Step-Down DC-To-DC Regulators

In modern electronic system design, the performance of power management modules has a direct bearing on the overall efficiency, reliability and space utilisation of the system. Mingjiada Electronics has long supplied the ADP2165/ADP2166 series of high-efficiency step-down DC-DC regulators, providing reliable power conversion solutions for sectors such as telecommunications equipment, industrial control, consumer electronics and instrumentation.

[ADI] The ADP2165/ADP2166 are high-efficiency, current-mode-controlled step-down DC-DC regulators that integrate a 19 mΩ high-side FET and a 15 mΩ synchronous rectification FET. Combining a compact 4 mm × 4 mm LFCSP package with precise current limiting, the ADP2165/ADP2166 enable smaller inductor sizes and high-power-density point-of-load solutions.
